The present study investigates the development of titanium dioxide (TiO2)/polyacrylonitrile (PAN) nanofiber membrane for the removal of nitrate from aqueous solution by photocatalysis. The TiO2 nanoparticles were synthesized by conventional sol–gel method followed by blending them into PAN polymer. The blended solution was electrospun into nanofiber using the co-electrospinning technique. The nanoparticle, PAN nanofibers and the TiO2 impregnated nanofibers were characterized using suitable techniques like X-ray diffraction, high-resolution transmission electron microscopy and scanning electron microscopy attached with energy dispersive X-ray spectroscopy. The average size and the diameter of the TiO2 nanoparticles and TiO2/PAN nanofibers were found to be 22 ± 0.32 nm and 90 ± 15 nm respectively. TiO2 nanoparticles and TiO2/PAN nanofibers showed maximum nitrate removal of 74.67 and 39% respectively at 10 mg/L nitrate concentration at pH 4. However at higher concentration (50 mg/L), the nitrate removal was found to be only 16.87%. The experimental data were fitted onto pseudo second-order kinetic model. The impregnation of TiO2 nanoparticles into the PAN nanofibers by co-electrospinning techniques lead to higher removal of nitrate in aqueous solution at lower concentration (10 mg/L and below). However at higher concentration, the TiO2/PAN nanofiber membrane was inefficient to remove nitrate.

The release of phenolic-contaminated treated palm oil mill effluent (TPOME) poses a severe threat to human and environmental health. In this work, manganese-modified black TiO2 (Mn-B-TiO2) was produced for the photodegradation of high concentrations of total phenolic compounds from TPOME. A modified glycerol-assisted technique was used to synthesize visible-light-sensitive black TiO2 nanoparticles (NPs), which were then calcined at 300 °C for 60 min for conversion to anatase crystalline phase. The black TiO2 was further modified with manganese by utilizing a wet impregnation technique. Visible light absorption, charge carrier separation, and electron–hole pair recombination suppression were all improved when the band structure of TiO2 was tuned by producing Ti3+ defect states. As a result of the enhanced optical and electrical characteristics of black TiO2 NPs, phenolic compounds were removed from TPOME at a rate of 48.17%, which is 2.6 times higher than P25 (18%). When Mn was added to black TiO2 NPs, the Ti ion in the TiO2 lattice was replaced by Mn, causing a large redshift of the optical absorption edges and enhanced photodegradation of phenolic compounds from TPOME. The photodegradation efficiency of phenolic compounds by Mn-B-TiO2 improved to 60.12% from 48.17% at 0.3 wt% Mn doping concentration. The removal efficiency of phenolic compounds from TPOME diminished when Mn doping exceeded the optimum threshold (0.3 wt%). According to the findings, Mn-modified black TiO2 NPs are the most effective, as they combine the advantages of both black TiO2 and Mn doping.
