Oxygen vacancy-rich defective Co <sub>3</sub> O <sub>4</sub> –RuO <sub>2</sub> heterostructure catalysts for efficient acidic oxygen evolution reaction
This study develops a Co<sub>3</sub>O<sub>4</sub>-RuO<sub>2</sub> heterojunction catalyst for the acidic oxygen evolution reaction (OER). The presence of oxygen vacancies at the heterointerface, along with the electronic coupling synergistically enhances OER activity. This results in a low overpotential of 218 mV at 10 mA cm<sup>-2</sup>, demonstrating its potential for efficient hydrogen production through proton exchange membrane water electrolysis.
