“…[5,6] Because of its high chemical stability, increased oxidation ability, improved photocatalytic activity, non-toxicity, and biocompatibility, ZnO was chosen as the photocatalyst to insert into the electrospun nanofiber membrane in this study., [7,[8][9][10] ZnO generally has a large band gap of ~3.37 eV with ~60 MeV exciton binding energy. [11,12] Overall, because of the aforementioned features, ZnO has been used in a wide variety of industries such as medicine carriers, cosmetics, fillers, gas sensors, spintronics, biosensors, photocatalysis, and among others. [11,13] However, it has been found that the key concerns with ZnO nanoparticles (NP) are their relatively poor efficiency, high band gap, quick recombination of excitons on active sites, and the requirement of UV light for activation, among other things.…”
