Modification of ZIF-8 using direct mixing method at a room temperature
2018
ZIF-8 modified with CNT doping have been successfully synthesized using direct mixing methods at room temperature. The characteristics of ZIF-8 and ZIF-8 with CNT were studied using XRD and SEM. The structural integrity and phase purity of both materials were obtained through X-ray diffraction patterns and was found comparable to that of sodalite-type ZIF-8. The peaks were found at 2θ = 7.4°, 16.5°, 22.1°, 25.7°, 26.7°, and 32.53°. When ZIF-8 was doped with CNT, the peaks of ZIF-8 decreased. Scanning electron microscopy of pure ZIF-8 showed hexagonal nanocrystals, and the particle sizes were distributed at approximately 50-140 nm. CNT-doped ZIF-8 showed that ZIF-8 attached to CNT was uniformly with diameters of approximately 80-120 nm. It was concluded that ZIF-8 modified using CNT had been succesfully synthesized.
