Abstract
The application discloses an X2H2 nano-catalyst rich in oxygen vacancies and a preparation method and application thereof in electrocatalytic reduction of carbon dioxide. The preparation method comprises the following steps: firstly, adding monohydrate citric acid into a solution containing copper salt and cerium salt, evaporating and concentrating the solution to form a sol, and then drying the gel to obtain a gel which is placed in a tube furnace for annealing, so as to obtain the X2H2 nano-catalyst rich in oxygen vacancies. The catalyst can be applied to electrocatalytic reduction of carbon dioxide to generate high-carbon products. The application has the characteristics of simple preparation operation, low cost and excellent performance (the selectivity is as high as 100%) in electrochemical reduction of carbon dioxide to ethylene and ethanol.
