“…− species [Eqs (13,14), (7)(8)(9)(10)(11)(12)]. Furthermore, a high concentration of Fe 3+ ions acts as the source of charge recombination for the photo-induced electrons and holes pair [Eqs (15)(16)(17)], which reduces the photocatalytic activity.…”

“…Furthermore, they are superior because of their excellent chemical stability, easy preparation, and low cost 7 . Hence, researchers have recently developed a lot of semiconductor metal oxide nano-photocatalysts, including Bi 2 O 3 , TiO 2 , ZnO, and Fe 2 O 3 , which are useful for keeping a comfortable climate for the human beings [8][9][10][11] . Among these semiconductor metal oxide photocatalysis, TiO 2 and ZnO are found quite suitable in photocatalytic process owing to their nontoxicity, wide bandgap, and high photosensitivity [12][13][14][15] .…”

“…Another advantage of the MSS method is the use of a low synthesis temperature (190-220 • C) and a short synthesis time compared to other methods enumerated in Table 2, which prevents uncontrolled NPs growth, formation of NPs aggregates as a consequence of sintering, and formation of foreign phase inclusions during NPs growth. It is generally known that ZnO codoping with Mn 2+ and Co 2+ ions causes a change in the optical properties and a reduction of the band gap width [103,105]. Figures 7 and 8 present a visual comparison of changes in the colours of Zn (1−x−y) Mn x Co y O samples depending on the content of dopants, while Table 7 summarises the results of the analysis of colours by the RGB and HSL colour models.…”

“…[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.…”
