Dual-functionalized ZIF-8 as an efficient acid-base bifunctional catalyst for the one-pot tandem reaction |
| 초록 |
An acid-base bifunctional zeolitic imidazolate framework, ZIF8-A61-SO3H, catalyst with amine and sulfonic acid groups was successfully prepared through two step post-synthetic modification: preparation of amine-functionalized ZIF-8 with amine contents of 61 % (ZIF8-A61), followed by the sulfonic acid functionalization. Amine-functionalized ZIF8-A materials with difference amine contents were also prepared by controlling the synthesis time. All obtained ZIF catalysts evaluated as a heterogeneous catalyst for a one-pot deacetalization-Knoevenagel condensation reaction. Compared with ZIF-8 and ZIF8-A catalysts, ZIF8-A61-SO3H catalyst showed good catalytic performance with 100 % conversion of the reactant and 98 % selectivity of the final product. Enhanced catalytic activity can be attributed to the co-existence of site-isolated acid-base groups on ZIF8-A61-SO3H catalyst in close proximity. The heterogeneous nature and reusability of the catalyst was confirmed. |
