We report an eco-friendly one-pot hydrothermal synthesis of ultrafine TiO2 nanocrystals (∼4.01 nm) homogeneously dispersed on the entire surface of graphene.
CuS caved superstructures with a variety of sizes and regular shapes were synthesized by an innovative one-pot method, which showed excellent catalytic properties evaluated by degradation of methylene blue (MB) without light.
