Zeolitic Imidazolate Framework (ZIF), a sub class of Metal-Organic Framework (MOF), has many advantages such as controllable porosity, high thermal stability, high chemical stability, and bone flexibility. ZIF materials are currently widely studied for the use in various applications: gas separation, gas sensor, gas storage, and catalytic reaction. Also, it can be used as a membrane reactor capable of separating gas and the reaction at the same time as it can act as a catalyst. In this research, we investigated solvothermal synthesis of polystyrene/Co-Zn bimetal ZIF core-shell particles and hollow bimetal ZIF particles. The Co-Zn bimetal ZIF shell thickness increased with the number of coating steps. To fabricate hollow bimetal ZIF particles, polystyrene cores of the polystyrene/bimetal ZIF core-shell particles were removed by washing them in DMF. As synthesized polystyrene/bimetal ZIF core-shell and hollow bimetal ZIF particles were characterized by XRD, FE-SEM, TEM, BET and TGA. |
