▎ 摘  要

NOVELTY - Preparing graphene quantum dot loaded bismuth vanadate nano composite material involves adding dopamine hydrochloride and graphene doper quantum dots/bismuth vanadate in a mol ratio of 1:10-15, adding into the reaction container, adding trihydroxymethyl aminomethane hydrochloride buffer solution, heating and stirring to obtain the target product GQDs load of bismuth vanadate nano composite material. USE - Method for preparing graphene quantum dot loaded bismuth vanadate nano composite material for efficiently degrading heavy metal ion. ADVANTAGE - The method enables to prepare graphene quantum dot loaded bismuth vanadate nano composite material that can effectively degrade heavy metal ion, can be widely applied to dye, heavy metal and microorganism polluted water purifying.
