一种BiVO4/InVO4异质结催化剂及其制备方法和应用
摘要：
本发明属于光催化领域，具体涉及一种BiVO4/InVO4异质结催化剂及其制备方法和应用。BiVO4/InVO4异质结光催化剂为液态钒源VOC2O4通过一步法与Bi(NO3)3·3.5H2O和In(NO3)3·4.5H2O水热形成5μm的内部为团聚花球外部为球状体。本发明产品对大肠杆菌、金黄葡萄球菌以及假交替单胞菌的杀菌率达到99％以上，对罗丹明B降解率达99.875％显著。目前该化合物已经在实验室合成，并且制备简单、易于控制、成本低廉，有效的构筑了可见光相应的BiVO4/InVO4异质结材料，加速了光生电子-空穴对的复合率。采用本发明的光催化剂，用量少、毒性小、效率高、持续作用时间长、可循环使用，能够有效的杀灭细菌以及降解染料，在水体净化领域具有广阔的应用前景。
摘要（英）：

The invention belongs to the field of photocatalysis and specifically relates to a BiVO4/InVO4 heterojunction catalyst as well as a preparation method and application of the BiVO4/InVO4 heterojunctioncatalyst. The BiVO4/InVO4 heterojunction catalyst is prepared to be 5mu m by hydrothermally synthesizing a liquid vanadium source VOC2O4, Bi(NO3)3.3.5H2O and In(NO3)3.4.5H2O by using a one-step method, the inner part of the BiVO4/InVO4 heterojunction catalyst is an agglomerated flower sphere, and the outer part of the BiVO4/InVO4 heterojunction catalyst is a spheroid. By using the product disclosed by the invention, the sterilization rate of Escherichia coli, staphylococcus aureus and pseudoalteromonas reaches 99% or above, and the degradation rate of Rhodamine B reaches 99.875%. At present,the compound is synthesized in a laboratory, in addition, the preparation method is simple in preparation, easy to control, low in cost, a visible-light response BiVO4/InVO4 heterojunction material iseffectively formed, and the composite ratio of photoelectron-hole pairs is increased. The photocatalyst disclosed by the invention is small in usage amount, low in toxicity, high in efficiency, longin lasting effect time, recyclable, capable of effectively killing bacteria and degrading a dye and wide in application prospect in the field of water body purification.
