Description
Summary:•A domestic microwave (DMW) was for synthesis of crystalline porous materials.•A simple, fast and low-cost synthesis of MOFs was developed.•The approach allowed the control of the solvent losses and temperature.•DMW uses timed and pulsed power as the control method of the heating process.•The produced MOFs showed excellent chemical properties. This work shows a facile modification of a modified domestic microwave oven that allows for the control of solvent losses and the monitoring of temperature during the synthesis of metal-organic frameworks (MOFs) MIL 100 under hydrofluoric acid-free conditions, HKUST-1 with unique properties, and MIL 88B. In order to obtain the best efficiency irradiation, a thermal mapping image from the domestic microwave DMW was obtained. The results showed that the chemical properties of the produced MOFs were excellent: the observed yield calculation and the BET surface area of the MIL-100 active crystals were 97% and 1300 m2g−1, respectively, and 90% and 1365 m2g−1, respectively for HKUST-1 with unique properties. A simple and low-cost alternative to a commercial microwave oven was developed, making it safer and its parameters controllable during the synthesis of MOFs.
