Abstract

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.
