摘要： The present disclosure discloses a preparation method of an organosilica/ceramic composite membrane with a gradient pore structure. The preparation method comprises: (1) selecting a porous ceramic material as a membrane support layer; (2) gradually replacing a solvent with water to prepare zirconium colloidal sols with different particle sizes, and successively coating the prepared zirconium colloidal sols onto a ceramic support from large to small so as to form a membrane transition layer with a gradient pore structure; and (3) catalytically synthesizing an organosilica polymeric sol using hydrochloric acid, coating the prepared organosilica sol onto the preheated transition layer through ultrasonic thermal spraying to undergo heat treatment, so as to prepare the organosilica/ceramic composite membrane with the gradient pore structure. According to the present disclosure, the transition layer with the gradient pore structure is prepared by using the zirconium colloidal sols with different particle sizes. An ultrathin defect-free organosilica separation layer is prepared through ultrasonic thermal spraying. As a result, the obtained organosilica/ceramic composite membrane can be applied to the fields of salt-containing dye wastewater treatment and polypeptide bioactive substance separation.

摘要： An inorganic structure body has a free-standing structure including a fibrous member and/or a shell. The fibrous member and/or the shell include a metal and/or an inorganic material and have a three-dimensionally continuous configuration. The free-standing structure may have a structure that is based on a nonwoven fabric or a porous membrane used as a substrate.

摘要： A support nanofunctionalised with photocatalytic nanoparticles made of polymeric material, preferably transparent or translucid, characterised by a nanoroughness, measured by means of an electron microscope, comprised between 10 and 150 nm and a macroroughness, measured by means of an electron microscope, comprised between 100 and 600 μm, wherein said nano and macro-roughness are diffused internally and/or superficially. A process for preparing the nanofunctionalised support is also described. Further, an use of the nanofunctionalised support as a photocatalyst activated by UV and/or visible light, for the decontamination of a fluid, preferably air and/or water, from organic contaminants, bacteria, moulds, odours and a combination thereof is described. Finally, a filtration device comprising at least one nanofunctionalised support of the invention associated with at least one source of UV and/or visible light configured to irradiate said at least one nanofunctionalised support is described.

摘要： The present disclosure provides a rigid self-supporting MXene separation membrane and a preparation method and use thereof, belonging to the technical field of membranes. In the present disclosure, a MXene material is mixed with an aluminum salt powder to conduct one-step membrane formation by hot-pressing. The pressure forms the powder into a membrane and imparts rigidity, enabling a self-supporting structure; the heating breaks an ionic bond of an inorganic metal salt to reach a molten ionic state, and free metal cations react with active oxygen-containing functional groups on the surface of the MXene to form new chemical bonds (such as an Al—O bond); such a chemical bond has higher energy, achieving a desirable anti-swelling effect to improve the membrane stability. The separation membrane further has excellent conductivity and hydrophilicity.
