In recent times, fibrous membranes have developed a role in the filtration of pollutants from air or water. Unfortunately, if the filter membrane is used for several hours or days, it leads to a gradually increasing concentration of pollutants on the membrane surface. However, this contamination can be effectively eliminated by the presence of photocatalytic submicroparticles (g-C3N4) as a part of fibrous membranes.
We prepared a set of polyvinyl difluoride (PVDF) fibrous photocatalytic membranes and compared their photocatalytic activities by phenol degradation in a batch reactor. Our results indicate the reusable properties up to 3 cycles and no visible membranes degradation.
