Metal organic framework derived In<sub>2</sub>O<sub>3</sub>/ZrO<sub>2</sub> heterojunctions with interfacial oxygen vacancies for highly selective CO<sub>2</sub>-to-methanol hydrogenation.
Ontology highlight
ABSTRACT: The hydrogenation of CO2 to methanol is a promising route for carbon capture and utilization, however achieving high selectivity and productivity remains a challenge. This study presents a novel catalyst synthesized by pyrolyzing a zirconium-based metal-organic framework impregnated with indium, yielding ultrafine In2O3 nanoparticles uniformly embedded within a ZrO2 and carbon matrix. The resulting In2O3/ZrO2 heterojunction exhibited abundant oxygen vacancies at the interface, which is crucial for enhancing the catalytic performance. Under gas-phase conditions, the catalyst achieves an exceptional methanol selectivity of 81% with a record-high productivity of 2.64 gMeOH·gcat⁻¹·h⁻¹ at mild reaction conditions, whil
