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).

In2O3 催化剂上 CO2 加氢的原位 DRIFTS 和 DFT 研究

研究了In ₂ O ₃上CO ₂加氢的压力依赖反应机理。 In ₂ O ₃上的CO ₂加氢只能在高压下生成甲醇，而常压操作会生成CO。在高压下，HCOO* 向H ₃ CO* 的转化加速，从而生成甲醇甲酸盐路线（CO ₂ * → HCOO* → H ₃ CO* → H ₃ COH）。
