Towards maximizing the InO/-ZrO interfaces for CO-to-methanol hydrogenation.

Through chelating-assisted impregnation with diethylenetriamine-pentaacetic acid (DTPA), we developed an efficient and durable CO hydrogenation catalyst, In15/-ZrO-DTPA, featuring improved InO reducibility and interfacial Zr-O-In structures. Benefiting from its distinct CO activation and hydrogenation ability, In15/-ZrO-DTPA exhibited remarkable CO-to-methanol catalytic activity, achieving up to 91% selectivity at 260 °C and 5.0 MPa, with consistent conversion maintained over 400 hours.

Oxygen vacancy promoted carbon dioxide activation over Cu/ZrO for CO-to-methanol conversion.

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.
