以In（NO3）3、硫脲和M（NO3）2（M = Zn和Cu）为原料，乙二胺为溶剂，采用水热法合成了Zn掺杂和Cu掺杂的In（OH）ySz纳米晶固溶体。通过X射线衍射（XRD）、紫外维斯漫反射光谱（DRS）和X射线光电子能谱（XPS）对样品进行了表征。虽然Zn掺杂和Cu掺杂的In（OH）ySz固溶体在丙酮和典型染料RhB的分解中表现出可见光驱动的光催化活性，但它们的光催化性能有很大差异。Cu掺杂的In（OH）ySz固溶体只能将丙酮和RhB分解为中间产物，不能将其矿化。而Zn掺杂的In（OH）ySz固溶体可以将丙酮和RhB矿化为CO2，其光催化活性比未掺杂的In（OH）ySz固溶体略有提高。密度泛函理论（DFT）计算的Zn掺杂和Cu掺杂的In（OH）ySz固溶体表明，引入...
Nanocrystalline Zn-doped and Cu-doped In(OH)ySz solid solutions were synthesized from In(NO3)3, thiourea, and M(NO3)2 (M = Zn and Cu) in an aqueous solution of ethylenediamine via a facile hydrothermal method. The samples were characterized by X-ray diffraction (XRD), UV−vis diffuse reflectance spectra (DRS), and X-ray photoelectron spectroscopy (XPS). Although both Zn-doped and Cu-doped In(OH)ySz solid solutions show visible-light-driven photocatalytic activities in the decomposition of acetone and typical dye like RhB, their photocatalytic performance is quite different. Cu-doped In(OH)ySz solid solution can only decompose acetone and RhB to intermediates, but cannot mineralize them. On the contrary, Zn-doped In(OH)ySz solid solution can mineralize acetone and RhB to CO2 and its photocatalytic activity is a little enhanced compared to that of the undoped In(OH)ySz solid solution. Density functional theory (DFT) calculations on Zn-doped and Cu-doped In(OH)ySz solid solutions reveal that the introduction ...
