Porous Liquids (PLs) is a new type of liquid material that combines the permanent porosity of porous solid materials and liquid fluidity, showing great potential for gas adsorption and separation, catalysis and other applications. Metal framework materials (MOFs) are expected to become one of the best candidates for constructing porous hosts for PLs due to their high specific surface area, thermal and chemical stability, unique structure, and simple preparation. In recent years, MOFs (ZIF-8, ZIF-67, UiO-66, etc.) based porous liquid related research has been continuously reported. First, the classification of porous liquids was presented. Secondly, we summarize the preparation of MOFs-based porous liquids and its applications in recent years. Finally, the challenges in the preparation of MOFs-based porous liquids and the future in the areas of gas adsorption and catalysis are prospected and summarized
