TiO2 decorated nano-fiber membranes for potential applications in CO2 filtration, sequestration, and conversion

TiO2 nanofiber membranes were produced for the potential purpose of CO2 filtration, sequestration, and energy harvesting. For increased photocatalytic activity, necessary for the conversion of CO2 into a form of energy, TiO2 (anatase) decorated nanofibers membranes were attained. Following the carbonization of sol-gel coated PVA nanofibers at temperatures ranging 300-600ºC, the presence of TiO2 anatase phase was confirmed by XRD and FTIR. In addition, the morphology, nano-fiber diameter, and 2D structured carbon webs corroboration were further analyzed using SEM. Brunauer-Emmett-Teller (BET) characterization analyzed the nano-fibers’ filtration and sequestration system of CO2 gas, allowing for thorough investigation of the absorption ability of the membranes. The production of TiO2 nano-fiber membranes was successfully achieved following the given techniques and methodology.
