然而,由于锐钛矿型 TiO 2 的禁带宽度为 3.2 ev,只对紫外光有吸收能力,限制了 TiO 2 在可见光下的光催化能力。随着人们对太阳能资源有效利用的迫切需求,为了拓宽 TiO 2 的光吸收宽度,人们通常通过采取金属(Fe [11] 、Ni、Cr等)/非金属(N [12] 、C、B、S等)的掺杂方式,加强 TiO 2 的光催化降解能力,将光吸收宽度扩大至可将光区域。最近,有报道关于N [13] 、S [14] 、C [15] 、F和N [16] 共掺杂到具有(001)面的锐钛矿 TiO 2 催化剂中,均表现出良好的可见光光催化性能。虽然,关于过渡金属 Fe 掺杂到 TiO 2 催化剂中的可见光催化性能研究已经报道很多 [11,17] ,但关于 Fe 元素掺杂的具有(001)面的锐钛矿 TiO 2 催化剂的紫外/可见光催化性能还未有人研究。而且,多级 TiO 2 纳米片通常具有很高的结晶度,通过利用温和的手段在后处理时进行掺杂不太可能,另外,在反应过程中通过添加掺杂剂的前体会对晶体的成核与生长产生很大影响以至于得不到我们预想的结构和形貌 [12] 。

摘要: 半导体光催化剂因可以直接利用太阳光进行光催化且不产生二次污染,成为一种应用于环境污染治理领域较为理想的材料。其中TiO2光催化剂具有较高的光稳定性、良好的化学性质、无毒、较低的成本、高的光催化效率等特点,目前受到广泛的研究与关注。然而,TiO2快速复合的电子-空穴及较大的禁带宽度等自身缺陷,导致其量子产率不高,TiO2中的电子只能在紫外光下被激发,这些因素使得它的光催化性能受到了制约。因此,近年来通过研究不同的金属元素掺杂TiO2基光催化剂及研究不同特殊微纳结构来克服TiO2自身缺陷以改善其光催化性能并取得较大的进展。研究发现,通过将不同金属(如Ag、Fe、Cu、Ce等)以一元、二元、多元的形式掺入TiO2中,可改善TiO2的自身缺陷,并在催化剂表面产生不同作用,使其光响应范围增大,光催化性能显著提升。此外,研究者们还发现,特殊微纳结构的存在可以加快金属掺杂TiO2基光催化材料的电子转移,从而提高TiO2光生电子-空穴的分离效率,增加了其量子产率。金属掺杂后,TiO2对有机物的降解率及其产氢能力、光能转化率都得到了显著的提高,使其不仅在紫外光下具有优异的性能,而且在可见光下也能进行良好的光催化。掺杂后TiO2的抗菌效果与防雾性能也得到了显著的提升。本文一方面综述了不同金属掺杂体系(一元、二元复合以及多元复合掺杂)对TiO2结构及其光催化性能的改变,总结不同制备工艺对TiO2结构与性能的影响规律,并分析光催化性能的增强机制。另一方面概述了金属掺杂TiO2基复合材料的一些特殊微纳结构包括石墨烯包覆结构、核-壳结构以及其他结构的制备工艺,并讨论了不同微纳结构与金属掺杂在增强TiO2光催化性能上所起的作用。最后简单综述了不同金属掺杂TiO2纳米复合材料的不同应用,展望了未来研究方向及�

考察了Pt促进的N掺杂TiO2(Pt/N-TiO2)催化剂对光催化降解有机污染物性能的影响及其作用本质.采用X射线衍射、透射电镜、X射线光电子能谱、紫外-可见漫反射光谱、光电化学和荧光光谱等手段对催化剂进行了表征,并考察了样品在可见光下光催化降解甲基橙(MO)的反应性能.结果表明,Pt的存在并未明显改变N-TiO2的晶相和介孔结构,却增强了催化剂对可见光吸收,但这种背景吸收不利于光激发中心(N-TiO2)对可见光的吸收,从而影响Pt/N-TiO2光催化活性;高度分散在N-TiO2表面的Pt,显著地改变了催化剂表面电子结构,从而提高了N-TiO2的光催化性能.%The influence of Pt as a promoter on the photocatalytic performance of nitrogen-doped TiO2 was described. The sample was characterized by X-ray diffraction. transmission electron microscopy, X-ray photoelectron spectroscopy, UV-Vis diffuse reflectance spectroscopy,photoelectrochemistry, and photoluminescence. The degradation of methyl orange in aqueous solution under visible light irradiation was used to evaluate the photocatalytic activity of the sample. The modification of N-TiO2 with Pt did not change the crystal structure and the mesoporous structure of TiO2. The loading of Pt enhanced the material absorption in visible light region, which is assigned to background absorption that has detrimental effect on photocatalytic activity. However, the highly dispersed Pt on the surface of N-TiO2 remarkably altered the surface structure (surface state) of N-TiO2. contributing largely to the enhanced photocatalytic activity of nitrogen-doped TiO2.

  1. 核心研究领域:研究的核心是“N掺杂TiO2”作为载体,负载“金属”纳米颗粒构成复合催化剂。这种改性策略旨在克服纯TiO2仅能利用紫外光的局限性,拓展其在可见光下的催化活性。
  2. 关键改性机理:N元素的掺杂能够有效减小TiO2的带隙,增强其对可见光的吸收能力。负载的金属(尤其是贵金属如Pt, Pd, Ru, Au)不仅可以作为活性位点,还能促进光生电子-空穴对的分离,抑制其复合,从而显著提高催化效率。N掺杂还能诱导强金属-载体相互作用(SMSI),进一步提升催化剂的活性和稳定性。
  3. 主要催化应用:该类催化剂被广泛应用于多个领域,包括:
    • 环境治理:光催化降解水体和空气中的有机污染物(如亚甲基蓝、苯酚、醛类挥发性有机物)。
    • 能源转换:光催化产氢(如甲酸脱氢)、CO2还原制备燃料。
    • 精细化工合成:选择性加氢反应(如硝基芳烃加氢)。
  4. 代表性催化体系:已有的研究覆盖了多种金属,特别是贵金属。例如,Pt/N-TiO2在选择性加氢和污染物降解中表现优异;AuPd/N-TiO2在甲酸脱氢产氢方面活性很高;Ru/N-TiO2则在CO2加氢等领域受到关注。

    • 提取要点:重点提取每篇论文的催化剂制备方法、关键结构表征结果(如金属粒径、N掺杂形式)、催化反应类型、性能数据(如转化率、选择性、周转频率)以及提出的催化机理。
  2. 构建研究报告框架并填充内容
    • 目标:搭建一个逻辑清晰的报告结构,并用上一步提取的信息填充各个模块。
    • 报告框架
      • 引言:概述TiO2光催化剂的优势与瓶颈,引出N掺杂与金属负载协同改性的重要性。
      • 核心催化体系剖析:分小节详细介绍不同金属(Pt, Pd, Ru等)负载N-TiO2催化剂的典型研究案例。每个案例将围绕“制备-结构-性能-机理”四个方面展开。
      • 共性机理探讨:综合不同研究,总结N掺杂与金属负载之间协同作用的普遍规律,如图解说明其如何增强光吸收、促进电荷分离和活化反应物。
      • 总结与展望:归纳该领域的研究现状,并对未来发展方向(如新型金属负载、机理的深入探究、实际应用挑战等)进行展望。
  3. 数据可视化与图表制作
    • 目标:为了使报告“图文并茂”,将关键信息转化为可视化图表。
    • 可视化方案
      • 创建对比表格:制作一个总结性的表格,横向对比不同论文中的催化剂体系、目标反应、关键性能指标和发表期刊/年份,使成果一目了然。
      • 绘制机理示意图:根据论文中的描述,绘制一幅通用的机理示意图,形象地展示在可见光照射下,电子如何从N掺杂的TiO2跃迁,并被金属纳米颗粒捕获,从而驱动催化反应的全过程。

Thus, N-doped TiO2 and two types of composites, N-doped TiO2/CNT and N-doped TiO2/rGO, were prepared by a new environmentally friendly one-pot method. CNT and rGO were used as supports, triethylamine and urea as N doping agents, and titanium (IV) tetraisopropoxide and ethanol as Ti precursor and hydrolysis agent, respectively. The as-prepared photocatalysts exhibited enhanced photocatalytic performance compared to TiO2 P25 commercial catalyst during the photoreduction of CO2 with water vapor. It was imputed to the synergistic effect of N doping (reduction of semiconductor band gap energy) and carbon support (enlarging e(-)-h(+) recombination time). The activity and selectivity of catalysts varied depending on the investigated material. Thus, whereas N-doped TiO2 nanoparticles led to a gaseous mixture, where CH4 formed the majority compared to CO, N-doped TiO2/CNT and N-doped TiO2/rGO composites almost exclusively generated CO. Regarding the activity of the catalysts, the highest production rates of CO (8 mu mol/gTiO(2)/h) and CH4 (4 mu mol/gTiO(2)/h) were achieved with composite N-1/TiO2/rGO and N-1/TiO2 nanoparticles, respectively, where superscript represents the ratio mg N/g TiO2. These rates are four times and almost forty times higher than the CO and CH4 production rates observed wi

然而,由于锐钛矿型 TiO 2 的禁带宽度为 3.2 ev,只对紫外光有吸收能力,限制了 TiO 2 在可见光下的光催化能力。随着人们对太阳能资源有效利用的迫切需求,为了拓宽 TiO 2 的光吸收宽度,人们通常通过采取金属(Fe [11] 、Ni、Cr等)/非金属(N [12] 、C、B、S等)的掺杂方式,加强 TiO 2 的光催化降解能力,将光吸收宽度扩大至可将光区域。最近,有报道关于N [13] 、S [14] 、C [15] 、F和N [16] 共掺杂到具有(001)面的锐钛矿 TiO 2 催化剂中,均表现出良好的可见光光催化性能。虽然,关于过渡金属 Fe 掺杂到 TiO 2 催化剂中的可见光催化性能研究已经报道很多 [11,17] ,但关于 Fe 元素掺杂的具有(001)面的锐钛矿 TiO 2 催化剂的紫外/可见光催化性能还未有人研究。而且,多级 TiO 2 纳米片通常具有很高的结晶度,通过利用温和的手段在后处理时进行掺杂不太可能,另外,在反应过程中通过添加掺杂剂的前体会对晶体的成核与生长产生很大影响以至于得不到我们预想的结构和形貌 [12] 。

摘要: 半导体光催化剂因可以直接利用太阳光进行光催化且不产生二次污染,成为一种应用于环境污染治理领域较为理想的材料。其中TiO2光催化剂具有较高的光稳定性、良好的化学性质、无毒、较低的成本、高的光催化效率等特点,目前受到广泛的研究与关注。然而,TiO2快速复合的电子-空穴及较大的禁带宽度等自身缺陷,导致其量子产率不高,TiO2中的电子只能在紫外光下被激发,这些因素使得它的光催化性能受到了制约。因此,近年来通过研究不同的金属元素掺杂TiO2基光催化剂及研究不同特殊微纳结构来克服TiO2自身缺陷以改善其光催化性能并取得较大的进展。研究发现,通过将不同金属(如Ag、Fe、Cu、Ce等)以一元、二元、多元的形式掺入TiO2中,可改善TiO2的自身缺陷,并在催化剂表面产生不同作用,使其光响应范围增大,光催化性能显著提升。此外,研究者们还发现,特殊微纳结构的存在可以加快金属掺杂TiO2基光催化材料的电子转移,从而提高TiO2光生电子-空穴的分离效率,增加了其量子产率。金属掺杂后,TiO2对有机物的降解率及其产氢能力、光能转化率都得到了显著的提高,使其不仅在紫外光下具有优异的性能,而且在可见光下也能进行良好的光催化。掺杂后TiO2的抗菌效果与防雾性能也得到了显著的提升。本文一方面综述了不同金属掺杂体系(一元、二元复合以及多元复合掺杂)对TiO2结构及其光催化性能的改变,总结不同制备工艺对TiO2结构与性能的影响规律,并分析光催化性能的增强机制。另一方面概述了金属掺杂TiO2基复合材料的一些特殊微纳结构包括石墨烯包覆结构、核-壳结构以及其他结构的制备工艺,并讨论了不同微纳结构与金属掺杂在增强TiO2光催化性能上所起的作用。最后简单综述了不同金属掺杂TiO2纳米复合材料的不同应用,展望了未来研究方向及�

摘要: 半导体光催化剂因可以直接利用太阳光进行光催化且不产生二次污染,成为一种应用于环境污染治理领域较为理想的材料。其中TiO2光催化剂具有较高的光稳定性、良好的化学性质、无毒、较低的成本、高的光催化效率等特点,目前受到广泛的研究与关注。然而,TiO2快速复合的电子-空穴及较大的禁带宽度等自身缺陷,导致其量子产率不高,TiO2中的电子只能在紫外光下被激发,这些因素使得它的光催化性能受到了制约。因此,近年来通过研究不同的金属元素掺杂TiO2基光催化剂及研究不同特殊微纳结构来克服TiO2自身缺陷以改善其光催化性能并取得较大的进展。研究发现,通过将不同金属(如Ag、Fe、Cu、Ce等)以一元、二元、多元的形式掺入TiO2中,可改善TiO2的自身缺陷,并在催化剂表面产生不同作用,使其光响应范围增大,光催化性能显著提升。此外,研究者们还发现,特殊微纳结构的存在可以加快金属掺杂TiO2基光催化材料的电子转移,从而提高TiO2光生电子-空穴的分离效率,增加了其量子产率。金属掺杂后,TiO2对有机物的降解率及其产氢能力、光能转化率都得到了显著的提高,使其不仅在紫外光下具有优异的性能,而且在可见光下也能进行良好的光催化。掺杂后TiO2的抗菌效果与防雾性能也得到了显著的提升。本文一方面综述了不同金属掺杂体系(一元、二元复合以及多元复合掺杂)对TiO2结构及其光催化性能的改变,总结不同制备工艺对TiO2结构与性能的影响规律,并分析光催化性能的增强机制。另一方面概述了金属掺杂TiO2基复合材料的一些特殊微纳结构包括石墨烯包覆结构、核-壳结构以及其他结构的制备工艺,并讨论了不同微纳结构与金属掺杂在增强TiO2光催化性能上所起的作用。最后简单综述了不同金属掺杂TiO2纳米复合材料的不同应用,展望了未来研究方向及�

The sample was characterized by X-ray diffraction. transmission electron microscopy, X-ray photoelectron spectroscopy, UV-Vis diffuse reflectance spectroscopy,photoelectrochemistry, and photoluminescence. The degradation of methyl orange in aqueous solution under visible light irradiation was used to evaluate the photocatalytic activity of the sample. The modification of N-TiO2 with Pt did not change the crystal structure and the mesoporous structure of TiO2. The loading of Pt enhanced the material absorption in visible light region, which is assigned to background absorption that has detrimental effect on photocatalytic activity. However, the highly dispersed Pt on the surface of N-TiO2 remarkably altered the surface structure (surface state) of N-TiO2. contributing largely to the enhanced photocatalytic activity of nitrogen-doped TiO2.

Thus, N-doped TiO2 and two types of composites, N-doped TiO2/CNT and N-doped TiO2/rGO, were prepared by a new environmentally friendly one-pot method. CNT and rGO were used as supports, triethylamine and urea as N doping agents, and titanium (IV) tetraisopropoxide and ethanol as Ti precursor and hydrolysis agent, respectively. The as-prepared photocatalysts exhibited enhanced photocatalytic performance compared to TiO2 P25 commercial catalyst during the photoreduction of CO2 with water vapor. It was imputed to the synergistic effect of N doping (reduction of semiconductor band gap energy) and carbon support (enlarging e(-)-h(+) recombination time). The activity and selectivity of catalysts varied depending on the investigated material. Thus, whereas N-doped TiO2 nanoparticles led to a gaseous mixture, where CH4 formed the majority compared to CO, N-doped TiO2/CNT and N-doped TiO2/rGO composites almost exclusively generated CO. Regarding the activity of the catalysts, the highest production rates of CO (8 mu mol/gTiO(2)/h) and CH4 (4 mu mol/gTiO(2)/h) were achieved with composite N-1/TiO2/rGO and N-1/TiO2 nanoparticles, respectively, where superscript represents the ratio mg N/g TiO2. These rates are four times and almost forty times higher than the CO and CH4 production rates observed wi

To address the limitations of carbon materials, such as high cost, low mechanical strength, and hydrophobic nature, Park et al*.* [57] developed a Ru SAC catalyst supported on N-doped TiO2. TiO2 was chosen for its stability, non-toxicity, and affordability, making it a practical alternative. Additionally, TiO2 is commonly used in photocatalysis and can be effectively doped with nitrogen, which can either be substitutional (Ns) or interstitial (Ni) introducing N-doped sites that facilitate the coupling of metallic species like Ru, ensuring effective dispersion and distribution of the metal catalyst within the support. Two methods were employed to synthesize the catalysts with melamine as the nitrogen source and different support precursors. The use of titanium isopropoxide (MN-TiO2) promoted the formation of both Ns and Ni sites (Fig. 11a), while titanium dioxide (N-TiO2) favored Ni sites (Fig. 11b). Various calcination temperatures were tested, with 773 K being selected based on XRD and XPS analyses. These analyses showed significant TiO2 network formation and effective N-doping due to thermal decomposition at this temperature. Additional characterization techniques confirmed the successful incorporation of Ru into the structure, its oxidation state as Ru+3, and the absence of Ru NPs, indicating a high level of atomic dispersion. In situ CO Diffuse Reflectance Infrared Fourier Transform (DRIFT) adsorption studies revealed the absence of characteristic CO bands at 1960 cm−1 as
