Abstract

Through chelating-assisted impregnation with diethylenetriamine-pentaacetic acid (DTPA), we developed an efficient and durable CO₂ hydrogenation catalyst, In15/m-ZrO₂-DTPA, featuring improved In₂O₃ reducibility and interfacial Zr-O-In structures. Benefiting from its distinct CO₂ activation and hydrogenation ability, In15/m-ZrO₂-DTPA exhibited remarkable CO₂-to-methanol catalytic activity, achieving up to 91% selectivity at 260 °C and 5.0 MPa, with consistent conversion maintained over 400 hours.
