Probing effective, highly active, and inexpensive electrocatalysts for the oxygen evolution reaction (OER) is of immense importance for water electrolysis. Transition metal chalcogenides have been developed as a new class of materials for energy storage and conversion owing to their distinctive properties, such as capacitance, conductivity, and redox behavior. We designed ruthenium cobalt sulfide over a carbon cloth (RuCoS 2 /CC) via electrodeposition followed by an immersion technique and applied it for the OER. Owing to the existence of binary active sites, heteroatoms, and synergetic effect between the transition metal chalcogenides and the carbon substrate, RuCoS 2/CC exhibited a lower overpotential, better Tafel slope, and excellent durability compared with CoS 2 /CC and previous studies. |
