“…MB is a cationic dye and shows better efficiency in the basic environment, attributed to strong electrostatic interactions between a negative catalyst charge and a dye (Meshkatalsadat et al, 2022). The results demonstrate that the removal efficacy of MB was relatively high in both basic and acidic media rather than in neutral medium ascribed to repulsion forces (Amanulla et al, 2022).…”

This research lays the groundwork for preparing graphene oxide (GO)-doped CaO nanocomposites for efficient antibacterial potential and dye degradation. The study aimed to reduce the recombination rate of the electron hole (e−/h+) of CaO and improve charge transfer. This issue can be minimized by doping high-surface area GO into CaO quantum dots (QDs). Herein, the one-pot co-precipitation technique has prepared various concentrations (1, 3, and 5 wt%) of GO-doped CaO. Characterization techniques were used to investigate optical, elemental analysis, microstructural, functional, and morphological properties. The addition of GO into QDs showed excellent catalytic activity (CA) to control sample CaO against methylene blue (MB) in basic and acidic media compared to the neutral media. The synergistic effect of morphological alternation attributed to an increase in the mechanism of CA upon doping. Various concentrations of GO to QDs promised remarkable bactericidal potency against Escherichia coli.

“…With strontium doping, the properties of thorium oxide can be effectively tuned, opening up possibilities for its utilization across a broad spectrum of technological applications. [11][12][13] The objective of this investigation is to effectively incorporate strontium-doped thorium oxide (SrThO 3 ) nanofillers into the PVA matrix, aiming for UV screening and photo-stabilization through spectral absorption and emission processes. A simple solution casting method was employed to develop PVA/SrThO 3 nanocomposites with varying filler concentrations (0.5, 1.0, 2.0, and 4.0 wt %).…”

“…Nanosized particles, with their unique properties, sustain the theory of Rayleigh scattering and maintain visible transparency even after effective doping. [13][14][15] Interaction studies between PVA polymer and SrThO 3 NPs were conducted using powder x-ray diffraction (P-XRD) characterization and Fourier transform infrared (FTIR) spectroscopy. The prime focus of the study, UV shielding efficacy, was determined by irradiating and degrading MB dye.…”

This investigation reveals the successful incorporation of strontium‐doped thorium oxide (SrThO3) NPs into polyvinyl alcohol (PVA) polymer nanocomposites. The fabrication process of these PVA nanocomposites entails utilizing varying amounts (0.5, 1.0, 2.0, and 4.0 wt%) of SrThO3 nanofillers through a straightforward solution casting technique. The microstructure and overall structure of the resulting polymer nanocomposites were analyzed using powdered x‐ray diffraction for crystalline structure and Fourier transform infrared (FTIR) spectroscopy for molecular composition. The introduced SrThO3 nanofiller demonstrates a strong affinity for the hydroxyl groups present in the PVA polymer, a phenomenon validated through FTIR spectroscopy. In order to comprehend the impact of doping, the surface morphology of the PVA polymer nanocomposites underwent examination via scanning electron microscopy. The absorption and transmission of light were quantitatively assessed using UV–visible spectroscopy. The excitation and emission behaviors of electrons in both the PVA and SrThO3‐doped PVA nanocomposites were scrutinized through photoluminescence spectroscopy. Furthermore, the extent of UV light absorption was investigated by studying the degradation of methylene blue dye, a substance known for its sensitivity to UV light. Results indicate that the intentional incorporation of SrThO3 NPs significantly enhances UV stability.

Abstractα-Fe2O3/Fe3O4/g-C3N4 nanocomposites were prepared in-situ by solution combustion as magnetically separable photocatalysts using ferric nitrate as oxidant, glycine as organic fuel, and g-C3N4. The effects of various amounts of iron oxides, on the magnetic, optical, and photocatalytic properties were explored by different characterization methods. The magnetite (Fe3O4) phase as ferrimagnetic material disappeared with the increase in ferric nitrate contents, leading to the decrease of magnetic properties. The bandgap energy decreased from 2.8 to 1.6 eV with the increase of the hematite (α-Fe2O3) phase.The photocatalytic results showed that the type and amount of iron oxides had a significant effect on the decolorization of methylene blue, rhodamine B and methyl orange dyes under visible-light irradiation. The activity of the nanocomposite sample containing 37 wt. % iron oxides was more effective than that of the pristine g-C3N4 sample to photodegrade the methylene blue, rhodamine B and methyl orange, respectively. Moreover, the nanocomposites exhibited a higher photocurrent density than that of the pristine g-C3N4, mainly due to their lower charge recombination rate.
