Interfacial engineering of a tri-phase CoFe/CoFeO_x/Co–Fe₃O₄electrocatalyst for promoting the oxygen evolution reaction

Abstract

Exploration of high-efficient and structurally stable electrocatalysts for electrocatalytic oxygen evolution reaction (OER) at anode by a simple and feasible strategy is remained challenging for achieving hydrogen production with low-energy...

Interfacial engineering to construct an IrOx/WO3 hetero-structured catalyst for efficient acidic OER catalysis

“…S7, ESI†) demonstrated that the IrO x /WO 3 could be the first-echelon electrocatalysts in OER catalysis. 28–30 In addition, at the overpotential of 350 mV, the delivered current density of IrO x /WO 3 (315.0 mA cm −2 ) could be 300 times that of IrO x /WO 3 · x H 2 O (1.1 mA cm −2 ) and 15 times that of commercial IrO 2 (22.0 mA cm −2 ). Meanwhile, as shown in Fig.…”

MoO2/Ni0.2Mo0.8N nanorods on nickel foam as a high performance electrocatalyst for efficient water oxidation

“…3,4 Despite Ru and Ir (including their oxides) being ideal catalysts for the OER, their high-cost and poor stability not only hinder their commercial application but also lead to the development of cost-effective catalysts, such as transition metal compounds. [5][6][7] Among various catalysts, heterogeneous transition metal oxide (TMOs) and nitride (TMNs) catalysts, including NiO/ CoN, 8 Ni 3 Mo 3 N-MoO 2 -NiO, 9 and CoO/CoN, 10 have been reported as OER catalysts. 11,12 This is because the TMOs are suitable for water adsorption, 13 while TMNs exhibit better electronic conductivity than the transition metal oxides.…”
