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.
