Abstract
A filtration membrane includes an alumina support; a polyamide network disposed on the alumina support and formed by polycondensation between piperazine (PIP) and isophthaloyl dichloride (IPC); and a polypyrrole-graphitic carbon nitride (PPy-G-C3N4) photocatalyst embedded in the polyamide network through covalent bonding, the PPy-G-C3N4 photocatalyst including nanosheets of graphitic carbon nitride (G-C3N4) embedded in a matrix of a polypyrrole (PPy) polymer. The membrane of the present disclosure can be used for separating oil and water.

A method of water and oil separation, the method comprising:
- filtering a mixture of water and oil through a filtration membrane to generate a water permeate, wherein the filtration membrane comprises:
- an alumina support,
- a polyamide network disposed on the alumina support and formed by polycondensation between piperazine (PIP) and isophthaloyl dichloride (IPC), and
- a polypyrrole-graphitic carbon nitride (PPy-G-C3N4) photocatalyst embedded in the polyamide network through covalent bonding, the PPy-G-C3N4 photocatalyst comprising nanosheets of graphitic carbon nitride (G-C3N4) embedded in a matrix of a polypyrrole (PPy) polymer.
