“…Several precious metals like platinum (Pt), iridium oxide (IrO 2 ), and ruthenium oxide (RuO 2 ) have been studied, but they suffer the problems of high cost and relative scarcity, limiting their widespread use [9]. Moreover, many other metal oxides, sulfides, phosphides, and their complexes based on Ni, Fe, Mo, Co, Cu, and Mn have been investigated for efficient water-splitting activity [7][8][9][10][11][12][13][14][15]. However, there are still many challenging issues to overcome like high overpotential, complicated synthesis processes, low current density, and electrochemical stability in acidic and alkaline media.…”

Double perovskites are known for their special structures which can be utilized as catalyst electrode materials for electrochemical water splitting to generate carbon-neutral hydrogen energy. In this work, we prepared lanthanide series metal-doped double perovskites at the M site such as M2NiMnO6 (where M = Eu, Gd, Tb) using the solid-state reaction method, and they were investigated for an oxygen evolution reaction (OER) study in an alkaline medium. It is revealed that the catalyst with a configuration of Tb2NiMnO6 has outstanding OER properties such as a low overpotential of 288 mV to achieve a current density of 10 mAcm−2, a lower Tafel slope of 38.76 mVdec−1, and a long cycling stability over 100 h of continuous operation. A-site doping causes an alteration in the oxidation or valence states of the NiMn cations, their porosity, and the oxygen vacancies. This is evidenced in terms of the Mn4+/Mn3+ ratio modifying electronic properties and the surface which facilitates the OER properties of the catalyst. This is discussed using electrochemical impedance spectroscopy (EIS) and electrochemical surface area (ECSA) of the catalysts. The proposed work is promising for the synthesis and utilization of future catalyst electrodes for high-performance electrochemical water splitting.

Developing abundant Earth‐element and high‐efficient electrocatalysts for hydrogen production is crucial in effectively reducing the cost of green hydrogen production. Herein, a strategy by comprehensively considering the computational chemical indicators for H* adsorption/desorption and dehydrogenation kinetics to evaluate the hydrogen evolution performance of electrocatalysts is proposed. Guided by the proposed strategy, a series of catalysts are constructed through a dual transition metal doping strategy. Density Functional Theory (DFT) calculations and experimental chemistry demonstrate that cobalt‐vanadium co‐doped Ni3N is an exceptionally ideal catalyst for hydrogen production from electrolyzed alkaline water. Specifically, Co,V‐Ni3N requires only 10 and 41 mV in alkaline electrolytes and alkaline seawater, respectively, to achieve a hydrogen evolution current density of 10 mA cm−2. Moreover, it can operate steadily at a large industrial current density of 500 mA cm−2 for extended periods. Importantly, this evaluation strategy is extended to single‐metal‐doped Ni3N and found that it still exhibits significant universality. This study not only presents an efficient non‐precious metal‐based electrocatalyst for water/seawater electrolysis but also provides a significant strategy for the design of high‐performance catalysts of electrolyzed water.
