Efficient microwave assisted synthesis of metal–organic framework UiO-66: optimization and scale up
A highly efficient and scalable microwave assisted synthesis of zirconium-based metal–organic framework UiO-66 was developed. In order to identify the best conditions for optimizing the process, a wide range of parameters was investigated. The efficiency of the process was evaluated with the aid of four quantitative indicators. The properties of the materials prepared by microwave irradiation were compared with those synthesized by conventional heating, and no significant effects on morphology, crystal size, or defects were found from the use of microwave assisted heating. Scale up was performed maintaining the high efficiency of the process.
