Multiwalled carbon nanotubes (MWCNTs) and titanium dioxide (TiO2) are used as nanofillers to produce photocatalytic membranes via in-situ colloidal precipitation method. The weight ratio of MWCNT:TiO2 were manipulated at 10:0, 5:5, and 0:10 with nanomaterials concentration of 0.1 g/L. The membranes were characterized by surface hydrophilicity, porosity and pore size, and surface charge. The membrane performance was assessed using dead-end membrane filtration method to determine water permeability, dye rejection, and fouling propensity. Pure TiO2 membrane improved water permeability by 22.57% due to increasing hydrophilicity and large porosity. For dye rejection, pristine membrane outperformed the nanocomposite membranes with a rejection of 25.52% due to the small membrane pore size by sieve mechanism. Lastly, all the nanocomposite membranes showed better antifouling properties with higher normalized flux for pure MWCNTs (0.6822), TiO2 (0.6781), MWCNT/TiO2 (0.7239) membranes relative to the pristine membrane (0.6039). The pure TiO2 membrane has the highest improvement in flux recovery (19.87%) due to dye photodegradation under UV light assisted in membrane cleaning and defouling. Overall, this study demonstrates that photocatalytic nanocomposite membrane can be produced via in-situ colloidal precipitation method. 2022-10-06T03:24:32Z 2022-10-06T03:24:32Z 2022-07 Article International Journal of Nanoelectronics and Materials, vol.15(3), 2022, pages 207-222 1985-5761 (Printed) 2232-1535 (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/76304 en Universiti Malaysia Perlis (UniMAP) |
