ZIF-67 and Al-TCPP were retain their crystallinity after the reaction, and we tried to coat ZIF- 67 and Al-TCPP on honeycomb cordierite. Compared with the pure ZIF- 67 powder, Cordierite@ZIF-67 had a better conversion rate ( 45 % v.s. 70 % ) and TOF ( 7 h-1 v.s. 90 h-1 ). It also had high activity in the catalysis of epoxide derivatives with high conversion ( 65 % - 89 % ). Subsequently, the catalyst was applied to the reusability measurement, and the average conversion rate remained 56 % in ten cycles. In particular, this catalyst does not require complicated separation for recycle, and can be recovered by solvent wash and drying, which shows its potential for industrial development.金屬有機骨架二氧化碳整體式催化劑MOFCO2Monolithetd
