“…11 However, the practical utilization of widely studied oxide semiconductor photocatalysts such as TiO 2 and ZnO has been hindered by their large energy band gaps, which limit their ability to absorb ultraviolet light. [12][13][14][15] Perovskites, especially alkaline earth stannates, have gained significant interest from researchers due to their lower level of chemical toxicity, friendliness toward the environment, amazing optical characteristics, and prolonged thermal and chemical stability. [16][17][18][19][20] Prominent examples of these alkaline earth stannates are ZnSnO 3 , BaSnO 3 , SrSnO 3 , and CaSnO 3 , which have served as photocatalysts.…”

“…The Er-doped ZnO nanoparticles are nano-sized, which results in a greater surface area than ZnO alone. Additionally, suitable crystal size and bad gap energy can enhance the material’s photocatalytic activity [ 122 ]. This may be contributing to the discoloration of the dye solutions.…”

We present a study on the green synthesis of undoped and Er-doped ZnO compounds using Mangifera indica gum (MI). A set of tests were conducted to assess the structure of the material. The tests included X-ray diffraction, Raman, and Fourier-transform infrared spectroscopy. Optical properties were studied using diffuse reflectance and photoluminescence. Morphological and textural investigations were done using SEM images and N2 adsorption/desorption. Furthermore, photocatalytic tests were performed with methylene blue (MB), yellow eosin (EY), and the pharmaceutical drug ibuprofen (IBU) under UV irradiation. The study demonstrated that replacing the stabilizing agent with Mangifera indica gum is an effective method for obtaining ZnO nanoparticles. Additionally, the energy gap of the nanoparticles exhibits a slight reduction in value. Photoluminescence studies showed the presence of zinc vacancies and other defects in both samples. In the photocatalytic test, the sample containing Er3+ exhibited a degradation of 99.7% for methylene blue, 81.2% for yellow eosin, and 52.3% for ibuprofen over 120 min. In the presence of methyl alcohol, the degradation of MB and EY dyes is 16.7% and 55.7%, respectively. This suggests that hydroxyl radicals are responsible for the direct degradation of both dyes. In addition, after the second reuse, the degradation rate for MB was 94.08%, and for EY, it was 82.35%. For the third reuse, the degradation rate for MB was 97.15%, and for EY, it was 17%. These results indicate the significant potential of the new semiconductor in environmental remediation applications from an ecological synthesis.

“…Selective doping can recast the band structure by generating quasi-stable energies 38 . Recently, sulphur dopants on g-C 3 N 4 , graphene sheets 39 , 40 and ZnO have been reported to improve photocatalytic applications 41 . Moreover, because of the significant difference in size and electronegativity between S and O, S dopants modifies the optical, electrical and photocatalytic properties of semiconductor oxide 42 .…”

In this work, sulphur doped copper ferrites (S-CuFe2O4) photocatalysts were successfully synthesized for the first time using the facile hydrothermal method. The as-synthesized photocatalysts were characterized through XRD, Raman, TGA, FT-IR, UV–Vis-DRS, SEM, EDX and PL techniques. The results revealed that doping with sulphur has been found to be a suitable alternative that causes strain in the lattices as anions replace the oxygen from the CuFe2O4 nanostructures. Due to sulphur dopants, photocatalysts are able to efficiently trap and transfer the photoinduced charges, which readily suppress charge recombination. A UV–Vis spectrophotometer was used to monitor the degradation of selective toxic organic dyes (RhB, CR, MO, and CV) in aqueous media. The dye degradation results provide evidence for the surprisingly superior performance of S-CuFe2O4 over pristine CuFe2O4. On the basis of its efficiencies, this work can be assigned as an excellent candidate for photocatalysis science.
