Enhanced catalytic reduction of 4-nitrophenol using magnetic Ni–Ag bimetal supported on reduced graphene oxide

Year: 2026

Type: article

Abstract: , which is 3.4 times that of the catalyst without GO. The enhanced catalytic activity of the Ni-Ag/rGO catalyst with 0.5 wt% rGO can be attributed to the improved dispersity of Ni-Ag bimetallic nanoparticles (NPs) and accelerated electron transfer between the catalyst and rGO. It is noteworthy that the Ni-Ag/rGO catalyst shows superior magnetic recyclability and stability, with maintenance of more than 90% of its catalytic activity after 10 cycles of catalysis experiments, suggesting that the Ni-Ag/rGO catalyst is a resource-saving, highly effective catalyst for reducing 4-NP.
