Facile Sol-Gel Synthesis of Graphene-Supported FeNi Nanocatalysts for Enhanced Oxygen Evolution Reaction.

ABSTRACT: The challenge of utilizing green energy sources remains relevant nowadays, especially in developing new catalysts for hydrogen production through complete water decomposition. For this purpose, an electrocatalyst based on an Fe-Ni alloy supported by graphene was synthesized. The catalyst was prepared by using the sol-gel technique. Physicochemical characterization showed that the main crystalline phase was the FeNi alloy with an equimolar ratio. EDS showed that the elements were well distributed on the graphene matrix. Analyzing the structural properties of the catalysts revealed that the GFeNi 1:1.0 catalyst, which has the smallest average crystalline size and lowest lattice strain, exhibited superior catalytic activity due to its high density of exposed active sites. This promotes excell
