Construction of a novel BiSI/MoS2 nanocomposite with enhanced visible-light driven photocatalytic performance

Author affiliations

Abstract

A facile hydrothermal method was applied to synthesize BiSI/MoS2 with efficient solar photocatalytic activity. BET surface area analysis, UV-Vis diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), photoluminescence spectroscopy (PL) and an X-ray diffraction method (XRD) contributed to the characterisation of the prepared samples. The degradation of crystal violet (CV) under visible-light illumination was scrutinized in order to evaluate the photocatalytic performance of the photocatalyst. Considerably, the activities of both single MoS2 and BiSI were less than that of the composite photocatalyst for photodegradation of CV. The high specific surface area, good electrical carrier mobility and advantageous absorption capability of BiSI/MoS2 resulted in the improved photocatalytic activity. This work provides a favorable approach for fabrication of visible-light responsive and more stable nanocomposite photocatalysts that can be applied in effective treatment of persistent pollutants in water.
