Copper-doped Bi 2 MoO 6 with concurrent oxygen vacancies for enhanced CO 2 photoreduction

Bi 2 MoO 6 catalysts doped by monovalence Cu with self-adapting O vacancies (Ov) are prepared. The optimal Bi 2 MoO 6 –10% Cu exhibits an outstanding CO evolution rate of 11.40 μmol g −1 h −1 , about 6 times higher than that of Bi 2 MoO 6 (1.94 μmol g −1 h −1 ).
