NOVELTY - Preparation of graphene quantum dot stabilized silver rhodium bimetallic nano particles comprises placing soluble starch in a container, adding deionized water, stirring, dissolving in an oil bath at 30-100 degrees C, pouring into a reaction kettle, reacting in oven at 100-200 degrees C for 2-10 hours, and centrifuging; and taking graphene quantum dot solution, adding sodium borohydride aqueous solution, stirring, adding mixed aqueous solution of silver nitrate and rhodium nitrate, and stirring under ice-water mixture of 0-3 degrees C. USE - The method is used for preparing graphene quantum dot stabilized silver rhodium bimetallic nano particles for p-nitrophenol catalytic degradation and catalytically degrading 4-nitrobenzenediazonium tetrafluoroborate (claimed). ADVANTAGE - The nanoparticles have simple in operation and mild in reaction conditions, are stable and small in particle size, and have good dispersion performance and catalytic performance than silver nanoparticles and ruthenium nanoparticles.
