| 제목 | Conversion Synthesis of ZIF-8 Membranes from ZnO Layer: Effect of reaction rate control |
| 초록 | As ZIF materials have their unique properties such as high surface area, tunable pore structure, thermal and chemical stability, they can be used in various applications including gas separation and catalysis. For synthesis of ZIF membranes, fixing sub-micron ZIF seed particles on the support is challenging and important. In this work, we synthesized ZIF-8 seed layer by combining ZnO coating on the support and the conversion synthesis of ZnO layer in H-mIm solution to ZIF-8 layer, followed by the secondary growth synthesis for ZIF-8 membranes. The effect of reaction parameters on conversion seeding had been investigated to control the reaction rate combining the dissolution rate of ZnO and the crystallization rate. ZIF-8 membranes prepared by conversion seeding showed the better coverage of seeding layer and gas separation properties compared with the membranes prepared by traditional dip-coating seeding. |
