Dual-defective-engineered RuO2/D-Co3O4/CC composite as efficient electrocatalysts for triggering oxygen evolution reaction in acidic media

Defect engineering is widely acknowledged as an effective strategy for improving catalyst performance by increasing the abundance of active sites and optimizing binding energies. Herein, dual-defective-engineered RuO2/D-Co3O4/CC composite was fabricated using a straightforward process involving electrodeposition and acid etching method to improve the oxygen evolution reaction (OER) with low Ru loading (2.42 wt%) in acidic media.
