Abstract

Bi₂WO₆ nanosheets with plentiful oxygen vacancies were synthesised, and were highly efficient for the electroredution of CO₂ to CO. The faradaic efficiency of CO could reach 91% with a high current density of 43 mA cm⁻² at low potentials. The oxygen vacancies could enhance the reaction effectively by improving the adsorption and activation of CO₂.
