Synergistic effect of surface hydroxyl anchoring and electronic metal-support interaction in Cu-ZnO-SrTiO3 catalysts for enhanced CO2 hydrogenation

Puntos clave

The research investigates how surface hydroxyl anchoring and electronic interactions enhance CO2 hydrogenation.
Analyzed the charge mediated anchoring mechanism to bind Cu²⁺ and Zn²⁺
Studied the effect of oxygen vacancies on catalyst structure
Compared catalytic activity using various oxygen vacancy densities.
Cu 0 step-edge sites enhanced H 2 adsorption, improving catalytic activity for methanol synthesis
Low-crystallinity SrTiO₃ with oxygen vacancies tuned the d-band center of Cu
Small Cu and ZnO particles were achieved through managing electron transfer.

Resumen

• The charge mediated anchoring mechanism at oxygen vacancies anchors Cu 2+ and Zn 2+ via electron transfer. • Oxygen vacancies induce highly dispersed small Cu with Cu 0 step-edge sites. and small ZnO particles. • Coordination-unsaturated Cu 0 step-edge sites serve as structural descriptors for the d-band center. • Upshifted d-band center enhances H 2 adsorption, boosting catalytic activity for methanol synthesis. • Low-crystallinity SrTiO₃ with rich oxygen vacancies offers a pathway to tune the d-band center of Cu.
