▎ 摘  要

NOVELTY - Soluble salt of semiconductor photocatalyst, sodium thiosulfate and water are uniformly mixed to obtain precursor solution. Polymer microspheres are added to graphene oxide dispersion liquid, completely dispersed, and mixed to obtain polymer microspheres-containing disperse system. Obtained system is added to precursor solution, stirred, and irradiated under ultraviolet light to obtain precipitate. Obtained precipitate is soaked in organic solvent, to obtain insoluble solid which is then dried and ground to obtain semiconductor photocatalyst/graphene oxide hollow ball composite. USE - Preparation of semiconductor photocatalyst/graphene oxide hollow ball composite (claimed). DETAILED DESCRIPTION - Soluble salt of semiconductor photocatalyst, sodium thiosulfate and water are uniformly mixed to obtain precursor solution. Graphite oxide is added to water and ultrasonically dispersed to obtain graphene oxide dispersion liquid. Polymer microspheres are added to graphene oxide dispersion liquid, completely dispersed, and mixed to obtain polymer microspheres-containing disperse system. The obtained dispersed system is added to the obtained precursor solution, and stirred to obtain a mix solution. The obtained mix solution is irradiated under ultraviolet light source to obtain precipitate. The obtained precipitate is completely soaked in an organic solvent, to obtain insoluble solid. The obtained solid is then washed, dried, and ground to obtain semiconductor photocatalyst/graphene oxide hollow ball composite.
