The synergistic integration of electrochemical reactions with an external magnetic field offers a powerful strategy for enhancing reaction performance. Herein, we introduce flexible and continuously adjustable to enhance acidic CO2 reduction (CO2RR) In electrolyte (pH = 0.91), the initial Faradaic efficiency (FE) CO2RR CO is only 18%, which can be increased 63.2% when 2 T applied. More importantly, introduction this enables continuous switching products in noncontact mode. Theoretical calculations demonstrate that application promotes adsorption at Ni sites inhibits hydrogen evolution (HER), ultimately activity selectivity. This work provides fresh insight into how

Abstract Electrocatalysis is fundamental to modern energy conversion, driving essential processes like water splitting, CO 2 reduction, nitrogen fixation, and biomass transformation. These reactions are pivotal for advancing sustainable solutions, enabling clean hydrogen production, efficient carbon recycling, valueadded chemical synthesis. However, most studies currently struggle achieve the industrially‐relevant current densities (>300 mA cm −2 ), alongside challenges in maintaining high product selectivity. Reactant enrichment strategies, which enhance local concentration of reactants at active sites, have emerged as a powerful solution these challenges. By optimizing reactant adsorption, strategies significantly reduce overpotentials while improving density This review highlights recent advancements electrooxidation (e.g., OER, electrocatalytic organic oxidation), well their application electroreduction /NO 3 − reduction). The integration multiple techniques, advanced operando methods, offers promising path toward achieving industrially relevant efficiencies selectivity, paving way next generation conversion technologies.

Abstract The rational manipulation of the surface reconstruction catalysts is a key factor in achieving highly efficient water oxidation, but it challenge due to complex reaction conditions. Herein, we introduce novel situ strategy under gradient magnetic field form catalytically active species on ferromagnetic/paramagnetic CoFe 2 O 4 @CoBDC core–shell structure for electrochemical oxygen evolution (OER). We demonstrate that Kelvin force from cores’ local modulates shells’ reconstruction, leading higher proportion Co 2+ as sites. These sites with optimized electronic configuration exhibit more favorable adsorption energy oxygen‐containing intermediates and lower activation overall catalytic reaction. As result, significant enhancement OER performance achieved large current density increment about 128 % at 1.63 V an overpotential reduction by 28 mV 10 mA cm −2 after reconstruction. Interestingly, removing external field, activity could persist over 100 h. This work showcases directional enhanced oxidation.

The external field-assisted hydrogen evolution reaction (HER), beyond modifying electrocatalysts themselves, has garnered significant research attention. However, achieving synergy between multiple fields to enhance the HER performance remains challenging and is not well-explored. Here, NiMnIn Heusler alloy thin films are fabricated using pulsed laser deposition on flexional Cu substrates. Due different adsorption free energy under tensile strain (TS) compressive (CS), most enhancement of electrocatalytic activities for film observed in 1.9% TS state, while CS state shows negative effects. Furthermore, when an magnetic field coupled tensile-strained film, total overpotential reduced by 28.6% at a current density −50 mA cm–2. This improvement attributed synergistic effect that enhances H stability accelerates H2 desorption process. work demonstrates effectiveness combining presents promising strategy advancing electrocatalysis.
