▎ 摘  要

NOVELTY - Preparing graphene-platinum composite nano-materials comprises coating graphene as a matrix material on quartz glass sheet, placing in a reaction chamber, vacuuming the reaction chamber, loading the platinum nanoparticle precursor into raw material bottle, introducing nitrogen as inert gas into reaction chamber and cyclically depositing at 30-300 cycles to obtain graphene-platinum composite nano-material. The temperature of the reaction chamber is 50-400 degrees C. USE - The graphene-platinum composite nano-materials is useful in degradation of environmental pollutants including methyl orange, magenta, phenols, halogenated hydrocarbons and/or aromatic hydrocarbons and their derivatives (all claimed). ADVANTAGE - The graphene platinum composite nano-materials has excellent degradation effect on environmental pollutants; and controls the thickness and particle size distribution of platinum particles to enhance the adsorption capacity on the graphene surface using the atom layer deposition method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene-platinum composite nano-materials obtained by above method; and (2) use method of graphene-platinum composite nano-materials in the degradation of environmental pollutants, comprising placing graphene-platinum composite nano-materials and environmental pollutants to be degraded into a container, magnetically stirring while avoiding light and air and then irradiating with ultraviolet lamps.
