Abstract The success of different heterogeneous strategies organometallic catalysts has been demonstrated to achieve high selectivity and activity in photo/electrocatalysis. However, yielding their catalytic mechanisms at complex molecule‐electrode electrochemical interfaces remains a great challenge. Herein, shell‐isolated nanoparticle‐enhanced Raman spectroscopy is employed elucidate the dynamic process, interfacial structure, intermediates copper hydroxide‐2‐2′ bipyridine on Au electrode ((bpy)Cu(OH) 2 /Au) during oxygen evolution reaction (OER). Direct molecular evidences reveal that (bpy)Cu(OH) oxidizes into Cu(III) bridges atoms via oxygenated species, forming (bpy)Cu(III)O ‐Au with oxygen‐bridged binuclear metal centers Cu(III)‐O‐Au for OER. As potential further increases, combines surface hydroxyl groups (*OH) form important intermediate Cu(III)‐OOH‐Au, which then turns Cu(III)‐OO‐Au release O . Furthermore, situ impedance proves lower resistance faster mass transport hydroxy enhance Theoretical calculations formation significantly modify elementary steps OER, resulting potential‐determining step ≈0.58 V than bare Au. This work provides new insights OER mechanism immobilized‐molecule development application renewable energy conversion devices.

Abstract High‐efficient and durable electrocatalysts for oxygen reduction evolution reaction (ORR/OER) are desirable to Zn‐air batteries (ZABs). However, most of catalysts in powder form with sole active sites remain challenging achieving the satisfactory bifunctional catalysis suffer from peeling off during long‐term operation. Herein, hybrid CoFe constructed containing nanoalloys (≈10 nm), clusters (< 2 single atoms on aerophilic carbon fiber membranes as binder‐free air cathodes ultra‐long‐life ZABs. In particular, high air‐permeability (0.2 s) can prevent blocking by O bubbles promote mass transfer. The theoretical experimental results confirm that hydrophilic 4 /CoFeOOH reconstructed surface mainly responsible OER. While nitrogen (N)‐doped matrix, they play a synergetic role optimizing adsorption energy enhance ORR activity. Thus, as‐prepared exhibit an ultra‐low ORR/OER potential gap (0.64 V). When further assembled freestanding air‐electrodes, it exhibits outstanding cycling lifespan 1200 155 h liquid‐ quasi‐solid‐state ZABs respectively, which fivefold twofold higher than those powder‐based (240/67 h).

Abstract Ni‐Mo‐based catalysts that exhibit well‐synergized and readily accessible catalytic sites are ideal for achieving efficient electrocatalysis. Herein, the synthesis of hollow Ni spheres with a hierarchical nanosheet surface modified by highly dispersed MoN urea electrolysis is reported. This based on design Mo‐Ni precursors featuring array surface, achieved through phosphomolybdic acid (PMo 12 )‐mediated reconstruction Ni‐BTC spheres. The optimized MoN‐Ni catalyst can effectively drive both oxidation reaction (UOR) hydrogen evolution at low potentials 1.37 V 191 mV, respectively, current density 100 mA cm −2 . electrolytic cell utilizing these sustain voltage 1.53 operate continuously over 220 h. X‐ray photoelectron spectroscopy (XPS) functional theory (DFT) analyses demonstrate established built‐in electric field facilitates electron transfer from to Ni, optimizing d‐band center consequently reducing barrier UOR. In situ electrochemical impedance (EIS) in Fourier‐transform infrared indicate promotes formation high‐valent sites, which accelerates UOR eletrolysis more environmentally friendly “carbonate” pathway.
