Operando Reconstruction toward Dual-Cation-Defects Co-Containing NiFe Oxyhydroxide for Ultralow Energy Consumption Industrial Water Splitting Electrolyzer

Yingxia Zhao et al.

Summary: Guided by density functional theory, the interaction of cation vacancies and dopants can manipulate d band centers, thus achieving near-optimal binding energies of the oxygenated intermediates and ultralow potentials. This principle is implemented experimentally by catalysis operando variations synthesis, where Mo leaching from high-entropy Co, Mo co-doped NiFe hydroxide precursors forms Co dopant and cation vacancy coexistent NiFe oxyhydroxide. Operando electrochemical spectroscopy reveals that dual-cation-defects promote the easier oxidation transition of metal sites, contributing to a low overpotential of 255 mV at 100 mA cm(-2). Furthermore, dual-regulated NiFe oxyhydroxide electrodes operate stably at 8 A in practical industrial electrolyzers with an ultralow energy consumption of approximately 4.6 kWh m(-3) H-2, verifying the feasibility of lab-constructed novel catalysts towards industrialization.

Strong-Proton-Adsorption Co-Based Electrocatalysts Achieve Active and Stable Neutral Seawater Splitting

Ning Wang et al.

Summary: Direct electrolysis of pH-neutral seawater to generate hydrogen faces an anodic competition issue between the chlorine evolution and the oxygen evolution reaction (OER), resulting in low current density and limited operating stability. In this study, a proton-adsorption-promoting strategy has been proposed to increase the OER rate, allowing for enhanced and stable neutral seawater splitting. Palladium-doped cobalt oxide (Co3-xPdxO4) catalysts exhibit the best performance with an OER overpotential of 370 mV at 10 mA cm(-2) in pH-neutral simulated seawater, outperforming Co3O4 by 70 mV. Co3-xPdxO4 catalysts also demonstrate long-term stability in neutral seawater, with 450 hours at 200 mA cm(-2) and 20 hours at 1 A cm(-2). Experimental and theoretical analyses suggest that the inclusion of SPA cations accelerates the rate-determining water dissociation step in the neutral OER pathway, while ruling out additional OER sites as a main factor.
