摘要
为了探究BiVO_(4)光催化剂性能的稳定性与及其在实际生活中的可用性,采用水热法通过NH_(4)VO_(3)和Bi(NO)·5H_(2)O为原料制备三维花状微球BiVO_(4)。对BiVO_(4)样品通过表征手段探究其结构性质以及形貌特征。以苯酚模拟废水作为目标污染物,通过光催化实验对目标污染物进行降解以验证BiVO的光催化效果,探究催化性能最好的三维花状BiVO_(4)的制备方法和工艺。设计对照实验,验证光照对实验的主要作用。通过淬灭实验,探究BiVO_(4)在光催化反应中主要的活性物质,最后设计循环实验,探究实际生活可用性。实验得出,降解速率为80.09%三维花状微球BiVO光催化剂且性能稳定并具有实际生活可用性。
In order to explore the stability and availability of BiVOphotocatalyst in real life. BiVO_(4) was prepared by using NH_(4)VO_(3)and Bi(NO)·5H_(2)O as raw material. The structural properties and morphological characteristics of BiVOsamples were explored by characterization means. With phenol simulation wastewater as the target pollutant, the target pollutant was degraded by photocatalytic experiments to verify the photocatalytic effect of BiVO_(4), and the preparation method and process of 3 D floral BiVO_(4) with the best catalytic performance were continuously explored. The control experiment was designed to verify the main effect of light on the experiment. Through the quenching experiment, the main active substance of BiVO_(4)in the photocatalytic reaction was explored, and finally the cycle experiment was designed to explore the actual availability of life. The results show that degradation rate of 80.09% 3 D floral microsphere BiVOphotocatalyst is stable and has real-life availability.
