In situ integration of bimetallic NiFe Prussian blue analogs on carbon cloth for the oxygen evolution reaction.

Abstract

This study develops a cost-effective strategy to integrate the bimetal NiFe Prussian blue analog (PBA) on carbon cloth (NFPB@CC) as a highly-active oxygen evolution reaction (OER) hybrid catalyst. NFPB@CC possesses abundant unsaturated metal active sites, with a low OER overpotential of only 332 mV and a low Tafel slope of 78 mV dec^-1 at 10 mA cm^-1.
