Integration of P84 and porphyrin–based 2D MOFs (M−TCPP, M = Zn, Cu, Co, Ni) for mixed matrix membranes towards enhanced performance in organic solvent nanofiltration

•Four porphyrin-based MOFs were synthesized as nanofillers for membrane fabrication.•2D porphyrin–based MOFs have high compatibility with the P84 polymeric matrix.•The optimal MMMs exhibited 3-folds enhancement in permeance without rejection loss.•Ultrasonic treatment of Cu-TCPP further increased dispersion and OSN performance.•Stable OSN performance (36 h) was observed for separating VB12/ethanol solutions.
