▎ 摘　　要

NOVELTY - Preparing composite catalyst comprises taking graphene oxide, titanium carbide nano powder, sodium molybdate, and nickel(II) oxide hollow microspheres, uniformly dispersing by ultrasound in alcohol solvent, then adding thiourea, ultrasonically dispersing and mixing, carrying out microwave heating reaction, recovering microwave heating reaction product, and post-processing the reaction product. USE - The composite catalyst is useful for photolysis of water in hydrogen production (claimed). ADVANTAGE - The composite catalyst: is assembled on the outer surface of NiO hollow microspheres, graphene oxide, titanium carbide, and molybdenum disulfide; can promote the separation of photo-generated carriers; ensures the performance of molybdenum disulfide to produce hydrogen by photolysis water; improves the photocatalytic activity of the catalyst; can efficiently use natural light, and ensures highly efficient photohydrolysis.
