Oxygen vacancy promoted carbon dioxide activation over Cu/ZrO₂for CO₂-to-methanol conversion

Abstract

Oxygen vacancy-enriched ultrafine tetragonal ZrO2 was introduced as a support for copper nanoparticles to enhance the energy effici- ency of CO2 hydrogenation for methanol synthesis. This approach generates the critical...

Towards maximizing the In2O3/m-ZrO2 interfaces for CO2-to-methanol hydrogenation

“…In15/ m -ZrO 2 exhibited peaks related to hydrogenated species ( e.g. , HCOO* and CH 3 O*) at 250 °C, 21 indicating a high energy barrier for the hydrogenation step. In contrast, In15/ m -ZrO 2 -DTPA exhibited intense signals of HCOO* and CH 3 O* even at a low temperature (150 °C), suggesting a much lower energy barrier for hydrogenation on this material.…”
