Abstract
A membrane including a polysulfone/polyethylene terephthalate (PSf/PET) support and an active layer on an outer surface of the PSf/PET support. The active layer comprises reacted units of a diacyl chloride compound, a tetra-amine compound, and a nanocomposite including graphitic carbon nitride and polypyrrole. The membrane of the present disclosure is self-cleaning following exposure to radiation and finds application in water decontamination and de-salination.
Claims20
A method for photocatalytically degrading an organic pollutant in an aqueous solution, comprising:
- exposing a photocatalytic membrane to the aqueous solution containing the organic pollutant to adsorb at least a portion of the organic pollutant onto the photocatalytic membrane;
- then
- irradiating the photocatalytic membrane with solar light to degrade the organic pollutant;
- wherein the photocatalytic membrane comprises:
- a polysulfone/polyethylene terephthalate (PSf/PET) support;
- and
- an active layer on an outer surface of the PSf/PET support,
- wherein the active layer comprises reacted units of:
- a diacyl chloride compound;
- a tetra-amine compound;
- and
- a nanocomposite comprising graphitic carbon nitride and polypyrrole.
