▎ 摘　　要

This paper introduces a two-step method for the synthesis of hybrid NiS2/TiO2-gyaphene nano-composites, which exhibited superior properties like photoactivity over single material. The as-prepared composites were characterized by XRD, UV-VIS absorbance spectra, SEM, tem, EDX, and BET analysis, revealing the uniform covering of the g,raphene nanosheet with NiS2 and TiO2 nanocrystals. Hence, in the photodeg,radation of methylene blue, a significant enhancement in the reaction rate was observed with NiS2/TiO2-graphene composites, compared to the pure TiO2 and NiS2-TiO2. The high activity can be attributed to the synergetic effects of high charge mobility, and red shift in absorption edge of NiS2/TiO2-graphene.
