Abstract
Rational engineering of oxygen vacancies in a metal oxide-based catalyst represents an effective strategy to regulate catalytic performances by influencing both their electrochemical active surface areas and the microelectronic structure. However, the precise control and modulation of the concentration and uniformity of oxygen vacancies on the catalyst surface still remains inadequately explored and poorly elucidated. Herein, we develop a facile and effective method to prepare a series of In2O3 nanorods with varying oxygen vacancy concentrations for efficient electrolytic CO2 reduction to formate. Experimental results and theoretical calculations reveal that the abundant oxygen vacancies in the In2O3 catalyst…
