Electrocatalytic reduction of CO2 into valuable fuels and chemical feedstocks in a sustainable environmentally friendly manner is an ideal way to mitigate climate change environmental problems. Here, we fabricated series self-supporting Bi-Sb bimetallic nanoleaves on carbon paper (CP) by facile electrodeposition method. The synergistic effect Bi Sb components the electronic structure lead high formate selectivity excellent stability electrochemical reaction (CO2RR). Specifically, Bi-Sb/CP electrode achieved Faradic efficiency (FEformate, 88.30%) at -0.9 V (vs RHE). FE remained above 80% broad potential range -1.3 RHE), while FECO was suppressed below 6%. Density functional theory calculations showed that Bi(012)-Sb reduced adsorption energy *OCHO intermediate promoted mass transfer charges. optimally adsorbed production inhibiting CO product pathway, thereby enhancing synthesis. Moreover, CO2RR performance also investigated flow-cell system evaluate its for industrial applications. catalyst can maintain steady current density 160 mA/cm2 -1.2 RHE) 25 h continuous electrolysis. Such generation flow cells has rarely been reported previous studies. This work offers new insights development electrodes reduction.

Abstract The development of efficient oxygen evolution reaction (OER) electrocatalysts is critical to overcome the efficiency bottleneck in hydrogen generation via water electrolysis. Hollow nanostructured materials have emerged as a hot topic for electrocatalysis research because their advantages, including abundant active sites, large contact area between catalyst and electrolyte, short transmission path. As highly stable OER electrocatalysts, cobalt‐based attracted more attention. In this work, cobalt metal/cobalt phosphides/nitrogen‐doped carbon composites (Co‐Co x P/NC) with hierarchical hollow structure are designed by using ZIF‐67 microspheres precursors. By coating ZIF‐8 on surface further carbonizing, nanowhiskers successfully formed spheres under catalytic effect Co nanoparticles at high temperature. subsequent phosphating process, solid nanocrystalline particles transformed into core–shell CoP 2 P account Kirkendall effect. Through optimization microstructure material synergistic transition metal, metal phosphide, nitrogen doping, overpotential optimal only 287 mV 10 mA cm −2 current density 1 m KOH.
