Solvothermal and hydrothermal methods are widely used for the synthesis procedures of ZIFs materials. Solvents such as dimethyl formamide (DMF), dimethyl formamide (DEF), methanol, and water were commonly used to synthesize ZIFs materials. They are critical for the synthesis of the desired materials. Water offers several advantages being a low-cost solvent and benign solvents for health and environmental concerns. However, few ZIF-membrane, such as ZIF-8 membranes, were synthesized using water as the solvent.
