One-pot synthesis of Pd-Au-alloy-nanoparticle-decorated graphene oxide functionalized with dodecahydrododecaborate cluster for rapid and complete reduction of 4-nitrophenol at room temperature

摘要

The treatment of nitroaromatics in wastewater is a significant issue that must be addressed because of their high cytotoxicity.The catalytic reduction of 4-nitrophenol(4-NP)to the widely used 4-aminophenol(4-AP)is an excellent method for 4-NP removal.However,performing this reaction is difficult.In this study,two-dimensional(2D)graphene oxide(GO)with oxygen-containing surface groups was used as a substrate for the in situ anchoring ofPdAu alloy nanocrystals.
