In this study, an In₂O₃/Co/C-N catalytic system was developed for selective methanol synthesis from CO₂ hydrogenation. The selectivity of methanol reached 95.9% at a CO₂ conversion of 4.6% at 225 °C, and it was still high (88.4%) at a CO₂ conversion of 9.4% at 300 °C and 2 MPa. In contrast, the use of two single In₂O₃ and Co/C-N catalysts with the mechanical mixing method produced methane with a selectivity higher than 80%. Thus, the appropriate proximity of In₂O₃ and Co/C-N is crucial. More importantly, our developed In₂O₃/Co/C-N catalyst demonstrated a highly stable activity and methanol selectivity without deactivation of any catalyst within 50 h at 300 °C, showing a promising application in methanol synthesis from CO₂ hydrogenation.

In ₂ O ₃ / Co / CN催化剂上CO ₂加氢选择性合成甲醇

在这项研究中，开发了一种In ₂ O ₃ / Co / CN催化系统，用于由CO ₂加氢选择性合成甲醇。在225°C时，CO ₂转化率为4.6％时，甲醇的选择性达到95.9％，在300°C和2 MPa下，CO ₂转化率为9.4％时，甲醇的选择性仍然很高（88.4％）。相反，在机械混合方法中使用两种单一的In ₂ O ₃和Co / CN催化剂可产生选择性高于80％的甲烷。因此，In ₂ O ₃和Co / CN的适当接近度至关重要。更重要的是，我们开发的In ₂ O ₃/ Co / CN催化剂显示出高度稳定的活性和甲醇选择性，且在300°C下50 h内没有任何催化剂失活，显示了在CO ₂加氢合成甲醇中的应用前景广阔。
