Efficient activation of CO at low temperature was achieved through the interface effect between InO and ZrO by their geometric and electronic effects. The results show that 75InO-25ZrO (InO : ZrO molar ratio of 3 : 1), as a catalyst for the reverse water gas shift reaction, can achieve 28% CO conversion with 96% CO selectivity at 400 °C, 0.1 MPa, a H : CO molar ratio of 3 : 1 and a gas hourly space velocity of 10 000 mL g h. FTIR experiments provide a basis for clarifying the pivotal role of formate (facilitated at InO-ZrO interface) in this reaction.
通过InO和ZrO之间的界面效应及其几何和电子效应，实现了CO在低温下的高效活化。结果表明，75InO-25ZrO（InO与ZrO的摩尔比为3:1）作为逆水煤气变换反应的催化剂，在400℃、0.1MPa、H:CO摩尔比为3:1、气体时空速为10000 mL g h的条件下，CO转化率可达28%，CO选择性为96%。傅里叶变换红外光谱（FTIR）实验为阐明甲酸盐（在InO-ZrO界面处得到促进）在该反应中的关键作用提供了依据。
