Towards maximizing the In 2 O 3 / m -ZrO 2 interfaces for CO 2 -to-methanol hydrogenation

Through chelating-assisted impregnation with diethylenetriamine-pentaacetic acid (DTPA), we developed an efficient and durable CO 2 hydrogenation catalyst, In15/ m -ZrO 2 -DTPA, featuring improved In 2 O 3 reducibility and interfacial Zr–O–In structures.

Description
Summary:Through chelating-assisted impregnation with diethylenetriamine-pentaacetic acid (DTPA), we developed an efficient and durable CO 2 hydrogenation catalyst, In15/ m -ZrO 2 -DTPA, featuring improved In 2 O 3 reducibility and interfacial Zr–O–In structures. Benefiting from its distinct CO 2 activation and hydrogenation ability, In15/ m -ZrO 2 -DTPA exhibited remarkable CO 2 -to-methanol catalytic activity, achieving up to 91% selectivity at 260 °C and 5.0 MPa, with consistent conversion maintained over 400 hours.
