In recent years, BiVO has drawn much attention as a novel photocatalyst given its excellent ability to absorb visible light. This work reports the development of Ag-modified BiVMoO composites through a facile hydrothermal synthesis with the subsequent photoinduced reduction of Ag at almost neutral pH conditions. Metallic Ag nanoparticles were deposited on the (040) facet of Mo-doped BiVO powders. The crystal structure and morphology of the as-prepared samples were studied by XRD and SEM analyses. Moreover, the photocatalytic performance of BiVO, Ag/BiVO, and Ag-modified BiVMoO were evaluated by the degradation of rhodamine B (RhB). The Ag/BiVMoO composite exhibited the most efficient photocatalytic performance. The present work provides greater insight into the application of BiVO in the field of photocatalysis.
近年来，BiVO作为一种新型光催化剂因其出色的可见光吸收能力而备受关注。这项工作报道了通过简便的水热合成法制备Ag修饰的BiVMoO复合材料，并随后在几乎中性的pH条件下对Ag进行光诱导还原。金属Ag纳米颗粒沉积在Mo掺杂的BiVO粉末的（040）晶面上。通过XRD和SEM分析研究了所制备样品的晶体结构和形貌。此外，通过罗丹明B（RhB）的降解评估了BiVO、Ag/BiVO和Ag修饰的BiVMoO的光催化性能。Ag/BiVMoO复合材料表现出最有效的光催化性能。本工作为BiVO在光催化领域的应用提供了更深入的见解。
