The remarkable contribution of oxygen vacancies has been revealed by the operando spectroscopies for methanol synthesis from CO2.ydrogeneration on the reducible metal oxide-supported copper catalysts. However, a challenge remains in the intrinsic understanding of the evolution and advantage of oxygen vacancies for methanol synthesis. Here we prepare the TiO2.x/Cu with different oxygen vacancy densities by adjusting the ball-milling frequency. At the optimal condition, a TiO2.x/Cu with more oxygen vacancies delivers an excellent methanol yield of 2..5 mmol g-1h-1at 300 °C with a selectivity of more than 70%. The combined analysis of experimental characterizations and theoretical calculations reveals that the mutual dispersions of TiO2.xand Cu driven by mechanical energy induce the electron rearrangement in the d orbital of the Ti atom and relax the Ti–O binding at the interface, which facilitates the formation of oxygen vacancies that further reduce the barrier of CO2.ydrogenation to*HCOO due to higher nucleophilicity of titanium ions.
