Abstract
Developing highly efficient OER catalysts is essential for producing hydrogen from water electrolysis to compensate for conventional fossil fuel shortages. Here, the oxygen-vacancy-rich heterostructure grown on the Ni foam (NF) (Co3O4@Fe-B-O/NF) is fabricated. The synergistic effect between Co3O4 and Fe-B-O has been proven effectively modulate the electronic structure and produce highly active interface sites, ultimately leading to enhanced electrocatalytic activity. Co3O4@Fe-B-O/NFrequiresan overpotential of 237 mV to drive 20 mA cm-2 in 1 M KOH, and 384 mV to drive 10 mA cm-2 in 0.1 M PBS, superior to most catalysts currently used. Moreover, Co3O4@Fe-B-O/NF as an oxygen evolution reaction (OER) electrode shows great potential in overall water splitting and CO2 reduction reaction (CO2RR). This work may provide effective ideas for designing efficient oxide catalysts.
