Toward efficient dye degradation and the bactericidal behavior of Mo-doped La2O3 nanostructures

Abstract: In this study, different concentrations (0, 0.02, 0.04 and 0.06 wt. %) of Mo doped onto La2O3 nanostructures were synthesized using one-pot co-precipitation process. The aim was to study the...

“…45–47 Generally, the PCA is influenced by the surface area of the nanocatalyst, as a large surface area provides more active sites, increases the number of redox reactions on the nanocatalyst surface and results in the degradation of MB. 48,49 The results show that the MB dye degrades maximally when treated with Ba-doped TiO 2 rather than with the TiO 2 QDs. For the Ba-doped TiO 2 photocatalysts, the possible charge separation mechanism is described as follows.…”

“…TiO 2 peak intensity observed at 414 nm demonstrated the high recombination rate of e --h + couples, which influence TiO 2 photocatalytic performance significantly. Furthermore, peak intensity was reduced, which indicates a lower charge recombination rate upon doping showed higher photocatalytic activity [34,35]. These emission transitions have been credited to unilaterally charged oxygen vacancies in TiO 2 and arise when a photogenerated h + mix with an etaking up oxygen vacancies [36].…”

“…Catalytic activity usually depends on the surface area, crystallinity, and morphology of QDs. In general, the catalyst having a wide surface area has shown higher catalytic effectiveness because the catalyst may provide more active sites, 60,61 and the pH of the solution has a significant impact on degradation efficiency. In acidic media, catalytic activity was higher, which might be assigned to increased H + ions production absorbed by the surface of the nanostructure.…”
