In this research, thin film nanocomposite (TFN) membranes were developed using novel polyethersulfone– molybdenum oxide (PES–MoO 3 ) nanocomposite substrate. The effects of MoO 3 nanoparticles on the PES substrate morphologies, surface roughness, hydrophilicity, and water permeability were investigated by measuring the water contact angles, scanning electron microscope (SEM) imaging, FT‐IR spectroscopy, and atomic force microscope (AFM) analysis. The MoO 3 nanoparticle modified membranes were used in the forward osmosis (FO) process with both PRO mode (the membrane active layer facing draw solution) and FO (the membrane active layer facing feed solution) mode. The results indicated enhanced water permeability of the modified membranes upon the MoO 3 addition, leading to significant enhancement in the water flux and the desalination performance.
