CAT-based mixed matrix membrane, preparation method and application

The invention belongs to the technical field of photo-thermal water production membrane preparation, and discloses a CAT-based mixed matrix membrane, a preparation method and application, the CNT-based mixed matrix membrane is prepared from Ti-CAT, CNT and PCMVIMX; three-dimensional network structure Ti-CAT is used as a water transmission channel, CNT is used as a sunlight absorber to increase the light absorption property of the film, PCMVIMX is used as a binding agent to crosslink Ti-CAT and CNT together by using the self-crosslinking property under the ammonia gas condition, and finally a compact photo-thermal water production film is formed. The water production membrane has good acid-base stability, excellent cycle performance and salt resistance. The membrane preparation method is simple and convenient, and the high-speed water production membrane can be rapidly prepared. The method disclosed by the invention is suitable for preparing a mixed matrix membrane of a porous material and a carbon material, a
