▎ 摘　　要

NOVELTY - A visible light photocatalytic composite material comprises graphene-like molybdenum disulfide:silver phosphate with mass ratio of 0.1:100-3:100 in which visible light photocatalytic composite material degrades 10 mg/L rhodamine B solution under 400-800 nm visible light irradiation with degradation rate of 40% after 4 minutes, 90% after 10 minutes, and 95% after 12 minutes. USE - A visible light photocatalytic composite material for degrading rhodamine B (claimed). ADVANTAGE - Visible light photocatalytic composite material has strong absorption characteristics invisible light region, and preparation is simple, easy, and low-cost and has mild conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of visible light photocatalytic composite material which involves placing graphene-like molybdenum disulfide in water solution, performing ultrasonic dispersion until homogenous to obtain graphene-like molybdenum disulfide dispersion, adding silver nitrate solid particles, performing ultrasonic dispersion to fully dissolve silver nitrate, heating in water bath at 50-80 degrees C, stirring, adding sodium phosphate solution dropwise, stirring and reacting in darkness, washing, and drying. DESCRIPTION OF DRAWING(S) - The drawing shows a graph of the photocurrent response of visible light photocatalytic composite material. (Drawing includes non-English language text).
