Abstract
Recently, the bimetallic AgNi alloy nanoparticles(NPs) have garnered considerable attention due to their exceptional properties. Herein in this work, we reported the synthesis of AgNi nano-alloy and MoO 2 NPs loaded on nitrogen-doped carbon nanotubes (MoO 2 @C-AgNi) through the combination of self-sacrificial template method with N 2 -protected thermal treatment. Owing to bimetallic AgNi, MoO 2 components as well as 1D tube-like structural advantages, the MoO 2 @C-AgNi nanocomposites demonstrated significantly enhanced catalytic efficiency in comparison to monometallic MoO 2 @C-Ni nanocomposites for the reduction of 4-nitrophenol(4-NP), maintaining their superior catalytic performance even after six consecutive cycles. Moreover, benefited from their facile separation by external magnet and their consequent recyclability, the resultant MoO 2 @C-AgNi composites exhibited promising potential for practical utilization on wastewater treatment . This research could potentially pave the way for the utilization of these bimetallic nanostructures in various catalytic applications.
