Realization of fast, efficient and continuous oil–water separation is of great significance for solving theproblem of oil pollution. We present here a facile hydrothermal strategy to synthesize a superhydrophilicplatanus fruit-like Ni@Ni(OH)2 hierarchical architecture (SI-PFHA). Additionally, superhydrophobicplatanus fruit-like Ni@Ni(OH)2 hierarchical architecture (SO-PFHA) is obtained through stearic acidmodification of SI-PFHA. Dual-channel separation system is integrated based on two superwettingmembranes. Such separation system is competent for continuous light/heavy oil–water separation withhighflux and high separation efficiency. Importantly, outstanding durability and reusability make thisseparation system a promising strategy for practical application in remediation of oily wastewater.

A simplified strategy for facilely fabricating antifouling graphite carbon nitride/silver phosphate (g-C3N4/ Ag3PO4) nanocomposite photocatalytic polyvinylidene fluoride (PVDF) porous membranes was developed for effective removal of rhodamine B (RhB). g-C3N4/Ag3PO4 heterojunction was strongly fixed to the interior of the PVDF membranes via phase inversion method. The membrane structure was analyzed by Fourier transform spectrophotometer (FT-IR). The morphology of the prepared membranes was investigated using scanning electron microscopy (SEM), EDX-mapping and atomic force microscopy (AFM), respectively. All prepared nanocomposite photocatalytic PVDF membranes exhibited a typically porous structure, and g-C3N4/Ag3PO4 nanocomposites were well dispersed inside the membranes. The obtained g-C3N4/Ag3PO4 heterojunction nanoparticle decorated PVDF membrane had a lower water contact angle of 79o and higher porosity of 85% than that of other two control membranes. The nanocomposite photocatalytic PVDF porous membranes had extremely high permeation flux over 1,083 L·m−2·h−1, and could be used for the removal of RhB. The removal efficiency of g-C3N4/Ag3PO4-PVDF membranes towards RhB solution under visible light irradiation reached 97%, higher than that of the pure PVDF membranes (41%) and g-C3N4-PVDF membranes (85%). Remarkably, the flux performance and flux recovery ratio (FRR) of membranes revealed that the g-C3N4/Ag3PO4- PVDF membranes could recover high flux after fouling, which presented better fouling resistance. Furthermore, the fabricated antifouling g-C3N4/Ag3PO4 nanocomposite photocatalytic PVDF porous membranes exhibited excellent recyclability. Therefore, it is expected that g-C3N4/Ag3PO4-PVDF membranes could provide an energy-saving strategy for effective removal of organic dyes wastewater and have a great potential for practical wastewater treatment in the future.
