| 概要 | This talk will mainly introduce our recent efforts in developing improved methanol synthesis catalyst from CO2. In the first work, we introduced an atomic Pd-promoted ZnZrOx solid solution catalyst, which shows enhanced rate of methanol and CO production compared to bare ZnZrOx. Up to 0.8 at.% Pd can be atomically dispersed in ZnZrOx, leading to more oxygen vacancies on the mixed oxide that foster methanol production. In the second work, we developed a strategy to promote ZnZrOx catalyst by incorporating hydrogen activation and delivery functions through optimized integration of ZnZrOx and Pd supported on carbon nanotube (Pd/CNT). In CO2 hydrogenation to methanol, Pd/CNT+ZnZrOx exhibits drastically boosted activity and excellent stability over 600 h on steam test, showing potential for practical implementation. Lastly, we will briefly touch upon CO2 hydrogenation to formate, and a new concept “Green Chemical Farming” to convert CO2 to food components involving catalytic steps. |
