英文摘要The reaction current density for the CO2 electroreduction to formate of indium-based catalysts cannot meet the needs of industrial applications. Herein, the nickel-doped indium oxide nanocrystals (similar to 7 nm) confined in carbon nanofibers (Ni-In2O3@C NFs) demonstrate a formate partial current density of over 350 mA cm(-2) at a moderate overpotential of 0.8 V, and particularly, the formate Faradaic efficiency (FE) is above 90% in a wide potential region from -0.6 to -1.0 V. More remarkably, a long-term stability of 55 h with an industrially relevant current density of similar to 200 mA cm(-2) can be achieved after improving hydrophobicity of gas diffusion electrodes (GDEs). Experimental results combined with DFT calculations confirm that the enhanced activity is attributed to the synergistic effect of nickel doping and carbon encapsulation in engineering the electronic structure of In2O3 nanocrystals, which enhances the adsorption strength of OCHO* intermediates and accelerates the charge transfer rate.
