通过微波进行具有锌、钴或铜的ZIF的合成。研究了金属中心对产物形貌和孔隙的影响。氮吸附/脱附到ZIF的密度泛函理论研究。ZIF-8、Zn/Co-ZIF-8和Cu/ZIF-8的微孔、介孔和大孔的范围分别为99.814 - 99.969%、0.055 - 0%和0.031 - 0.130%。ZIF-8、Zn/Co-ZIF-8和Cu/ZIF-8的平均孔径分别为1.291、1.194和1.164 nm。氮在ZIF-8、Zn/Co-ZIF-8和Cu/ZIF-8上的单层饱和极限分别为21.152、18.943和17.784 mmol/g。此外，结果包括ZIF-8、Zn/Co-ZIF-8和Cu/ZIF-8的密度、总表面积、总孔体积和平均粒度。
Synthesis of ZIF with zinc, cobalt, or copper was carried out by microwaves. The effect of metal center on morphologies and pores of products was studied. Nitrogen adsorption/desorption onto ZIFs was examined by density functional theory. The micro, meso, and macropores of ZIF-8, Zn/Co-ZIF-8, and Cu/ZIF-8 ranged 99.814–99.969%, 0.055–0%, and 0.031–0.130%, respectively. Average pore sizes of ZIF-8, Zn/Co-ZIF-8, and Cu/ZIF-8 are 1.291, 1.194, and 1.164 nm, respectively. Monolayer saturation limits of nitrogen onto ZIF-8, Zn/Co-ZIF-8, and Cu/ZIF-8 were 21.152, 18.943, and 17.784 mmol/g, respectively. Further, the results included densities, total surface areas, total pore volumes, and average particle sizes of ZIF-8, Zn/Co-ZIF-8, and Cu/ZIF-8.
