Abstract:
Pollution by organic dyes has received extensive attention due to their high toxicity, biohazard, and high stability in the natural environment, and the development of high‐efficiency dye degradation and heavy metal ion reduction technologies is urgently needed in photocatalysis. However, the interface microenvironment between catalyst and pollutant is often ignored, and the poor compatibility of the catalyst‐pollutant interface constrains further efficient catalysis. Herein, to improve the compatibility of the catalyst‐pollutant interface, a surfactant‐capping strategy for enhanced photocatalysis of rhodamine B (RhB) on one‐dimensional rod‐like Bi 2 S 3 nanocrystals was investigated. Specifically, polyvinylpyrrolidone (PVP)‐capped Bi 2 S 3 (Bi 2 S 3 ‐PVP) showed enhanced RhB degradation rate compared with pure Bi 2 S 3 , and further studies suggested enhanced reaction interface compatibility at the Bi 2 S 3 ‐PVP‐RhB interface. This work provides an interface microenvironment modulation strategy for improving photocatalytic performance towards organic dyes.
