P123-Modified Synthesis of BiOCl Nanosheet/Bismuth Nitrate Heterojunctions for Photocatalytic Pollutant Degradation

Abstract

Given that currently more high-efficiency photocatalysts are needed to address environmental pollution, this paper has proposed an effective method of P123-modified synthesis of BiOCl nanosheet/bismuth nitrate (BiOCl/BBN) heterojunctions. The photocatalytic results showed that the BiOCl nanosheet with BiOCl/BBN heterojunctions (BOC-1) exhibited 100% efficiency in the photocatalytic degradation of RhB within 3 min under visible light, simultaneously demonstrating beneficial stability and recyclability. The effectiveness of the photocatalytic activity of BOC-1 was ascribed to the formation of BiOCl/BBN heterojunctions and P123 modification, which facilitated the separation of carriers. This study offers a convenient and effective approach for the synthesis of high-efficiency heterogeneous photocatalysts for the removal of environmental pollutants.
