TGA curves of GO nanosheets, ZHS nanoparticles, and ZHS/GO nanohybrids under air condition with raising rate of temperature of 10 °C/min. The mass loss of ZHS/GO is less than that of GO nanosheets and more than that of ZHS nanoparticles, respectively, which further indicates ZHS nanoparticles decorated on the surface of GO nanosheets
