Abstract Electrocatalytic hydrogenation of unsaturated aldehydes to alcohols is a promising alternative conventional thermal processes. Both the catalyst and electrolyte deeply impact performance. Designing electrode‐electrolyte interface remains challenging due its compositional structural complexity. Here, we employ electrocatalytic 5‐hydroxymethylfurfural (HMF) as reaction model. The typical cationic surfactant, cetyltrimethylammonium bromide (CTAB), analogs are employed additives tune interfacial microenvironment, delivering high‐efficiency HMF inhibition hydrogen evolution (HER). surfactants experience conformational transformation from stochastic distribution directional assembly under applied potential. This oriented arrangement hampers transfer water molecules promotes enrichment reactants. In addition, near 100 % 2,5‐bis(hydroxymethyl)furan (BHMF) selectivity achieved, faradaic efficiency (FE) BHMF improved 61 74 at −100 mA cm −2 . Notably, microenvironmental modulation strategy applies range reactions involving aldehyde substrates. work paves way for engineering advanced interfaces boosting alcohol electrosynthesis efficiency.

Abstract Single‐component electrocatalysts generally lead to unbalanced adsorption of OH − and urea during oxidation reaction (UOR), thus obtaining low activity selectivity especially when oxygen evolution (OER) competes at high potentials (>1.5 V). Herein, a cross‐alignment strategy in situ vertically growing Ni(OH) 2 nanosheets on 2D semiconductor g‐C 3 N 4 is reported form hetero‐structured electrocatalyst. Various spectroscopy measurements including experiments indicate the existence enhanced internal electric field interfaces vertical nanosheets, favorable for balancing intermediates. This heterojunction electrocatalyst shows high‐selectivity UOR compared pure , even V) large current density. The computational results show could steer increase urea, efficiently avoiding poisoning strongly adsorbed active sites. A membrane electrode assembly (MEA)‐based electrolyzer with anode operate an industrial‐level density 200 mA cm −2 . work paves avenue designing high‐performance by cross‐alignments components.
