Abstract
AbstractThe electronic structure of composites plays a critical role in photocatalytic conversion, whereas it is challenging to modulate the orbital for an efficient catalyst. Herein, we regulated thet2gorbital occupancy state of Ti to realize efficient CO2conversion by adjusting the amount of photo‐deposited Cu in the Cu/TiO2composite. For the optimal sample, considerable electrons transfer from the Cudorbital to the Tit2gorbital, as proven by X‐ray absorption spectroscopy. The Raman spectra results also corroborate the electron enrichment on the Tit2gorbital. Further theoretical calculations suggested that the orbital energy of the Ti3dorbital in TiO2is declined, contributing to accepting Cu 3d electrons. As a result, the Cu/TiO2composite exhibited an extremely high selectivity of 95.9 % for CO, and the productivity was 15.27 μmol g−1 h−1, which is almost 6 times that of the original TiO2. Our work provides a strategy for designing efficient photocatalysis as a function of orbital regulation.
