Reporter learned from the Chinese Academy of Sciences, Hefei Institute of Physical Science, Institute of Applied Technology Tian Xingyou, Zhang Xian R & D team in the nano-photocatalytic material recycling and functional fabric coating made new progress.Relevant research has been published in the international Journal "Cellulose" on.
Among many pollutant management technologies, photocatalytic materials are effective in the degradation of pollutants under the action of sunlight. Various photocatalytic nanomaterials have been studied for the purification of liquid or gaseous pollutants and are considered as the most promising But how to recycle these materials is the key issue.Considering the structural characteristics of loose and porous cotton fabric and the advantages of hydrophilic, natural and widely used, the research group successfully built a nano-template with its load template Photocatalytic fabric coating, to achieve the recovery of nano-photocatalytic material reuse, and through the layers of nano-photocatalytic material assembly, a substantial increase in photocatalytic efficiency.
The coated fabric has excellent photodegradation activity on both liquid and gaseous pollutants. Under the simulated sunlight, all the coated fabrics can effectively degrade pollutants (such as formaldehyde) and liquid pollutants (such as rhodamine etc.) ), Demonstrating excellent photocatalytic activity of degrading gases and liquid contaminants.
Due to the excellent characteristics of the material, on the one hand, it is used for purifying photocatalytic woven fabric by recycleable water, especially for the treatment of urban black-odor water body, decomposing and deodorizing toxic organic substances in the water body, increasing water body content On the other hand, the photocatalytic functional fabric made of curtains, sofa cushions, rugs and other textiles, giving it excellent degradation of formaldehyde and other gas pollutants, antibacterial Anti-UV and other features to achieve the unique effect of purifying indoor air, in the home textiles or automotive interior textiles and other fields to show attractive prospects.
