1. 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.
