Abstract The water (H 2 O) dissociation is critical for various H O‐associated reactions, including gas shift, hydrogen evolution reaction and hydrolysis corrosion. While the d ‐band center concept offers a catalyst design guideline O activation, it cannot be applied to intermetallic or main group elements‐based systems because Coulomb interaction was not considered. Herein, using corrosion of Mg as an example, we illustrate role dipole catalysts dissociation. kinetics can enhanced x Me y ( =Co, Ni, Cu, Si Al) catalysts, generation rate Ni‐loaded reached 80 times high Mg. adsorbed molecules strongly couple with Mg− , lowering barrier. dipole‐based mechanism applicable non‐transition metal‐based systems, such 17 Al 12 offering flexible strategy controllable

The use of magnetic fields as external stimuli to improve the kinetics electrochemical reactions is attracting substantial attention, given their potential reduce energy losses. Despite recent reports showing a positive effect on catalytic performance upon applying field working electrode, there are still many uncertainties and lack experimental evidence correlating presence electrocatalytic performance. Here, we present combination spectroscopic tools that demonstrate how an alters reaction mechanism oxygen evolution (OER), accelerating overall Ni4FeOx electrode. Complementary has been gathered supporting participation this microscopic effect. Electrochemical impedance spectroscopy (EIS) points speed-up intrinsic kinetics, independent other indirect effects. In same direction, spectro-electrochemical fingerprint intermediate species appear during cycle, detected under operando conditions, indicates change in order function hole accumulation. All these data confirm direct influence at origin magnetically enhanced OER.
