Abstract

The invention belongs to the technical field of nanometer material synthesis, and a carbon-quantum-dot-modified indium-sulfide (beta-In2S3) mesoporous hollow microsphere photocatalyst is synthesized in one step by utilizing a simple rapid hydrothermal method. The method comprises: dissolving indium chloride and L-cysteine in distilled water, and stirring to obtain a solution D; adding carbon quantum dot into the solution D, and stirring to obtain a solution E; transferring the solution E to a reaction kettle with a teflon inner liner, putting in a baking oven, and reacting at 150 DEG C for 24 h; and naturally cooling to room temperature, centrifuging to obtain a dark-red solid, washing and drying in vacuum, so as to obtain a sample. The indium-sulfide mesoporous hollow microsphere photocatalyst is applicable to degrade methyl orange dye under visible light.
