Modulation of the Interfacial Charge Density on Fe2p–Cop by Coupling Ceo2 for Accelerating Alkaline Electrocatalytic Hydrogen Evolution Reaction and Overall Water Splitting

Identifying the intrinsic active site in bimetallic Co3S4/Ni3S2 feathers on MXene nanosheets as a heterostructure for efficient oxygen evolution reaction

“…[11][12][13][14][15] Thus, developing an earth-abundant water oxidation catalyst with the properties of low-cost, effectiveness, high energy efficiency, and long-term durability is of great importance for improvement of the sluggish kinetics of OER. 16,17 Hence, researchers have concentrated on the design of alternative OER catalysts based on 3d transition metals, for instance, forming mixed metal oxides, 18,19 sulfides, [20][21][22] selenides, [23][24][25] nitrides, 26-28 phosphides, 29,30 their hybrids [31][32][33] and so on. Among the above alternatives, transition metal sulfides (TMSs) with semiconductor properties and better conductivity can facilitate the charge transfer process, 34 and are regarded as the most promising candidate to replace precious metals.…”
