NOVELTY - Method for preparing graphene quantum dot stabilized noble metal nanoparticle catalyst involves (i) taking glucan, adding water, stirring and dissolving, pouring into a reaction kettle and reacting for 6-15 hours at 100-200 degrees C to prepare a graphene quantum dot solution, (ii) adding water into the graphene quantum dot solution, uniformly stirring, dripping a noble metal salt solution and fully stirring to be uniform, (iii) dripping an ammonia borane aqueous solution, stirring and reacting for 0.5-3 hours and (iv) storing at 3-5 degrees C after the reaction is completed. USE - The method is useful for preparing graphene quantum dot stabilized noble metal nanoparticle catalyst used for catalyzing hydrogen production in response to energy crisis and environmental pollution and catalytically degrading p-nitrophenol. The gold nanoparticles is used as a pollutant for degradation of p-nitrophenol in industrial wastewater. ADVANTAGE - The method prepares the noble metal nanoparticles that can stably exist in an aqueous solution and have excellent water dispersibility, excellent catalytic activity and uniform particle size. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the catalyst for catalyzing hydrogen production by hydrolyzing a hydrogen source comprising ammonia borane, sodium borohydride or tetrahydroxydiboron and catalytically degrading p-nitrophenol.
