The unique performance of the enzyme is mainly achieved via weak interactions between "outer coordination sphere" and substrate. Inspired by this process, we developed 3D encapsulated-structure catalysts with hydrogen-bond engineering on shell, which mimics an enzyme. Various hydrogen bond acceptors (C═O, S═O, N–O groups) are imparted in shell. Concentration-dependent 1H NMR, inverse-phase gas Chromatography (IGC) measurements, DFT calculations underscore that strength acceptor groups alcohol follows order C═O < S═O N–O. hydroxyl compound oxidation rate vs a volcano behavior, reminiscent Sabatier's principle. variation among attributed to adsorption proposed bioinspired design principle expands scope encapsulated catalysts, enabling fine regulation catalytic activity through precise microenvironment control substrates.

Electrochemical conversion has been regarded as an ideal technology for achieving clean and sustainable energy, showing significant promise in addressing the increasingly serious energy crisis environmental pollution. Ru-containing electrocatalysts (RUCE) outperform other precious metals due to elevated intrinsic activity superior cost-effectiveness, developing into a promising candidate electrochemical reactions. A challenge field of catalyst discovery lies its heavy reliance on empirical methods, rather than approaches that are rooted rational design principles. This review first concentrates catalytically active sites critical factors governing catalytic performance durability. Then, comprehensive summary multifunctional modification strategies ranging from nanoscale atomic scale is explored control structure improve performance. By unveiling roles each component modified RUCE at level, their identified discussed establish structure-performance relationship catalysts. Finally, challenges perspectives Ru-based materials hydrogen, oxygen, nitrogen reactions presented inspire further efforts toward understanding meet ever-growing demand future.

Abstract Hydrogen production via seawater electrolysis is limited by chloride corrosion and slow oxygen evolution reaction (OER) kinetics. Here, we present hydroxyl network‐engineered NiFe hydroxide catalysts on stainless steel (SS‐NiFe‐X) a rapid one‐step electrodeposition strategy. During OER, the layer transforms into an active NiFeOOH/NiOOH phase, while in situ ‐generated surface networks establish hydrogen‐bond‐mediated pathways that simultaneously enhance OER activity shield against attack. SS‐NiFe‐60, with 500 nm oxide layer, sustains 400 mA cm −2 for over h aggressive environment (1.0 M KOH + 2.0 NaCl), bare SS experiences complete deactivation within 1 h. Operando studies reveal network could block penetration electrostatic repulsion facilitate intermediate adsorption, validated membrane electrode assembly electrolyzer stably delivering 250 100 This scalable design bridges mechanistic insights industrial applications.
