Study on Application of Inorganic Membrane in Desalination

At present, the problem of water shortage has become a global concern. Inorganic membranes have good chemical stability, corrosion resistance, high mechanical strength, and can be used under severe conditions such as high temperature, which makes them have broad application prospects in the field of desalination. In addition to traditional ceramic films, carbon-based material has gradually become research hotspots in the field of inorganic films due to their tunable nanostructures and excellent properties. In order to better understand the characteristics of different types of inorganic membranes and expand the application of inorganic membrane materials in desalination, this article firstly elaborated the classification, physical and chemical properties, preparation methods and retainment mechanism of inorganic membranes in detail; Secondly, the progress in application of desalination of inorganic membranes was summarized; Finally, the development of inorganic membranes in the future in the field of water treatment was prospected.
