Abstract Transition metal/p‐block compounds are regarded as the most essential materials for electrochemical energy converting systems involving various electrocatalysis. Understanding role of p‐block element on interaction key intermediates and interfacial water molecule orientation at polarized catalyst‐electrolyte interface during electrocatalysis is important rational designing advanced modified metal electrocatalysts. Herein, taking a sequence ruthenium phosphides (including Ru 2 P, RuP ) model catalysts, we establish volcanic‐relation between P‐proportion alkaline hydrogen oxidation reaction (HOR) activity. The dominant P regulating hydroxyl binding validated by active sites poisoning experiments, pH‐dependent infection‐point behavior, in situ surface enhanced infrared absorption spectroscopy, density functional theory calculations, which could tailor d‐band structure Ru, optimize adsorption across Ru−P moieties, thereby leading to improved proportion strongly hydrogen‐bonded facilitated proton‐coupled electron transfer process, responsible HOR performance.

Water is a salient component in catalytic systems and acts as reactant, product and/or spectator species the reaction. Confined water distinct local environments can display significantly different behaviors from that of bulk water. Therefore, wide-ranging chemistry confined provide tremendous opportunities to tune reaction kinetics. In this review, we focus on drawing connection between properties kinetics for heterogeneous (electro)catalysis. First, are presented, where enthalpy, entropy, dielectric be regulated by tuning geometry hydrophobicity cavities. Second, experimental computational studies investigate interactions inorganic materials, such carbon nanotubes (1D confinement), charged metal or oxide surfaces (2D), zeolites metal–organic frameworks (3D) ions/solvent molecules (0D), reviewed demonstrate opportunity create structures with unique H-bonding network properties. Third, role structure dynamics governing activation free energy, reorganization energy pre-exponential factor (electro)catalysis discussed. We highlight emerging enhance proton-coupled electron transfer optimizing interfacial H-bond networks regulate decarbonization chemicals fuels.
