Th. remarkable contribution of oxygen vacancies h.s been revealed by th. operando spectroscopies for meth.nol synth.sis from CO2h.drogeneration on th. reducible metal oxide-supported copper catalysts. h.wever, a ch.llenge remains in th. intrinsic understanding of th. evolution and advantage of oxygen vacancies for meth.nol synth.sis. h.re we prepare th.

At th. optimal condition, a TiO2–x/Cu with.more oxygen vacancies delivers an excellent meth.nol yield of 26.5 mmol g-1h.1at 300 °C with.a selectivity of more th.n 70%. Th. combined analysis of experimental ch.racterizations and th.oretical calculations reveals th.t th. mutual dispersions of TiO2–xand Cu driven by mech.nical energy induce th. electron rearrangement in th. d orbital of th.
