  Zirconium and silver co-doped TiO2 nanoparticles as visible light catalyst for reduction of 4-nitrophenol, degradation of methyl orange and methylene blue

  摘要：

  Catalytic activity of Zr and Ag co-doped TiO2 nanoparticles on the reduction of 4-nitrophenol, degradation of methylene blue and methyl orange was studied using sodium borohydride as reducing agent. The nanoparticles were characterized using X-ray diffraction, energy dispersive X-ray, high resolution transmission electron microscopy, selected area electron diffraction and UV-Vis spectroscopy. The rate of the reduction/degradation was found to increase with increasing amount of the photocatalyst which could be attributed to higher dispersity and small size of the nanoparticles. The catalytic activity of Zr and Ag co-doped TiO2 nanoparticles showed no significant difference even after recycling the catalyst four times indicating a promising potential for industrial application of the prepared photocatalyst.

  bacterial semiconductor particles means that, in principle, they are capable of performing a variety of photoredox reactions. The reactions involving photoelectrochemical indicators such as methyl viologen (MV2+) and methyl orange (MO−) are considered and, by comparing initial rates of reaction and altering reaction variables, a general mechanism of photoactivity for the cadmium sulfide ‘bio-semiconductor’

  肺炎克雷伯氏 菌会根据生长培养基中镉离子的存在在细胞表面形成电子致密的硫化镉颗粒（直径约5–200 nm）。在当前的研究中，这些“生物半导体”粒子已通过UV-VIS吸收和发光分析进行了光谱表征。观察到的光谱性质表明，它们的大小相似，并具有类似于通过常规化学方法制备的CdS系统的光敏性状。细菌半导体颗粒的光学性质意味着，原则上它们能够进行各种光氧化还原反应。涉及光电化学指示剂的反应，例如甲基紫精（MV 2+）和甲基橙（MO−）被考虑，并通过比较反应的初始速率和改变反应变量，提出了硫化镉“生物半导体”的光活性的一般机理。

  for the reduction of O2 by a conductance band electron was ca. 40–50 times smaller than that for the reduction of methyl orange by e–. Corrosion studies indicated that photoreduction of methyl orange to a hydrazine derivative (D3–) sensitised by CdS, was accompanied by anodic corrosion of the semiconductor even in the presence of EDTA. In this work the role of EDTA (at pH 4.4) appeared to be as a mediator

  硫化镉（CdS）粉末分散体已被用于在水溶液中pH <7的条件下敏化甲基橙（D –）的光还原。添加了许多电子供体（PVA，TEOA，硝酸盐，酒石酸盐，半胱氨酸，柠檬酸盐，乙酸盐和EDTA），但在pH 4.4时，仅EDTA显着提高了甲基橙的光还原速率。建立了稳态方程，该方程成功地描述了观察到的甲基橙光还原初始速率随甲基橙，光子，EDTA和O 2浓度（如果存在）的变化。从这项工作已表明对于孔（H速率常数+）通过清除EDTA是CA。比h +之间的重组反应大19000倍和一个电导带电子（e –）。此外，用于降低的O的速率常数2由导带电子是CA。比通过e –还原甲基橙要小40–50倍。腐蚀研究表明，即使在有EDTA的情况下，甲基橙也会被CdS敏化为CdS敏化的肼衍生物（D 3–），并伴随着半导体的阳极腐蚀。在这项工作中，EDTA（在pH为4.4时）的作用似乎是反应的媒介（省略了图示），而不是“理想的”牺牲电子供体。讨论了其原因。
