Oxygen vacancy-enriched ultrafine tetragonal ZrO was introduced as a support for copper nanoparticles to enhance the energy efficiency of CO hydrogenation for methanol synthesis. spectroscopic techniques confirmed the oxygen vacancy-mediated single-electron CO activation. The resulting highly efficient catalyst yielded a methanol production rate of 550 mg g h at 200 °C, outperforming state-of-the-art Cu-based catalysts.
