Because of their high surface-area porosity, MOFs have been studied for use in gas storage/separation/purification, catalysis and drug carrier. Most synthesis mythologies are hydrothermal or solvothermal, which are different from adding water or organic solvent in reaction. Especially, solvothermal is using organic solvents which most of them are toxic and non-eco-friendly such as dimethylformamide. So in this study, we are going to introduce how to synthesis UiO-66 in water-acid phase. UiO-66 is one of MOFs which reticular structure is consist of zirconium or hafnium clusters and they coordinate with twelve organic linker molecules. The coordinate linkers are terephthalic acid or similar coordinate linkers, such as fumaric acid, could get iso-reticular structure. In this work, we used dimethyl terephthalic acid, derivatization of terephthalic acid, react with zirconium chloride under high temperature and microwave radiation condition (140 °C; 10 minutes). However, amorphous crystalline material was obtained by terephthalic acid as linkers in the same condition. So we interested in the distinct phenomenon and resorted to a hypothesis and further study with a series experiments.
