▎ 摘　　要

NOVELTY - Preparing macroscopically recoverable molybdenum disulfide/graphite phase carbon nitride/graphene oxide composite material comprises (i) mixing the graphite phase carbon nitride and molybdenum disulfide, grinding to obtain a mixed sample, adding obtained mixed sample into the solvent and grinding to obtain a graphite phase carbon nitride and molybdenum disulfide dispersion, and dispersing graphene oxide uniformly in water to obtain a dispersion liquid of graphene oxide; (ii) uniformly mixing the obtained dispersion of graphite phase carbon nitride and molybdenum disulfide and the obtained dispersion of graphene oxide, adding L-ascorbic acid and uniformly dispersing to obtain a uniform dispersion; (iii) reacting the obtained homogeneous dispersion to obtain a hydrogel sample; and (iv) washing and drying obtained hydrogel sample. USE - The method is useful for preparing macroscopically recoverable molybdenum disulfide/graphite phase carbon nitride/graphene oxide. ADVANTAGE - The material solves the problem that the graphite-phase carbon nitride is easy to agglomerate and avoids the problem that the traditional powder material photocatalytic difficult to be recycled. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for composite material prepared by the above mentioned method.
