Abstract

The pressure dependent reaction mechanism of CO₂ hydrogenation over In₂O₃ was investigated. CO₂ hydrogenation on In₂O₃ can produce methanol only at high pressure, while the atmospheric pressure operation leads to the formation of CO. The conversion from HCOO* to H₃CO* is accelerated at high pressure, leading to the formation of methanol with the formate route (CO₂* → HCOO* → H₃CO* → H₃COH).
