Enhanced bifunctional electrocatalytic activities of hybrid Co(OH)2/MOF-derived materials for green hydrogen production by electrochemical water splitting

Three alkaline electrolyzers with Co 3 O 4 @NF and Co 3 S 4 @NF were fabricated for sustainable green H 2 production. The electrode materials demonstrated excellent performance in the OER, HER, and overall water splitting, coupled with robust durability.
