▎ 摘　　要

Tin selenide (SnSe) particles and SnSe-graphene composites were fabricated using a facile hydrothermal method. SnSe acted as a photocatalytic semiconductor material attached with graphene inducing excellent photocatalytic activity. The characterizations of composites were studied by X-ray diffraction (XRD), Scanning electron microscope (SEM), Transmission electron microscope (hEM), and with Energy dispersive X-ray (EDX). Moreover the Raman spectroscopic analysis was also observed of the SnSe-graphene composites with graphene oxide (GO) which has been previously established. The photocatalytic activity of SnSe-graphene was evaluated by measuring the photocatalytic degradation of organic pollutants such as methylene blue (MB), industrial dyes such as Texbrite BA-L (TBA) and Texbrite MST-L (TMST) under visible light. The photocatalytic degradation was analyzed using UV/Vis Spectrophotometer. The kinetic studies were also conducted to determine the order and the rate of the photocatalytic degradation of the organic dyes.
