Selective electroreduction of carbon dioxide (CO2) into multicarbon products using copper-based catalysts, primarily governed by CO adsorption configurations such as atop-adsorbed *CO (COatop) and bridge-adsorbed (CObridge), is a promising strategy for converting greenhouse gases valuable chemicals fuels. However, the production ethanol (C2H5OH), crucial chemical feedstock, significantly limited weak CObridge on catalysts. Herein, Cu2O-TiO2 heterostructure catalyst was designed to adjust promoting selectivity ethanol. At an applied potential −0.7 V vs RHE, demonstrated 5.1-fold increase in Faradaic efficiency (FE) C2H5OH (27.13%) compared that Cu2O (5.2%). Experimental theoretical calculation results verified strong electronic interactions between TiO2 Cu2O-TiO2, resulting valence state Ti consequently enhancing oxophilicity TiO2. Moreover, monoxide temperature-programmed desorption (CO-TPD) results, situ Raman spectra, DFT calculations revealed more robust surface than due improved TiO2, which responding better electrocatalytic CO2 reduction reaction (CO2RR). This work offers original insights design electrocatalysts selective from CO2RR engineering configurations.
