Effects of rare earth, transition and post transition metal ions on structural and optical properties and photocatalytic activities of zirconia (ZrO2) nanoparticles synthesized via the facile precipitation process

Novel solar-light-driven Z-scheme BiOCl@WS2 nanocomposite photocatalysts for the photocatalytic removal of organic pollutants

“…At periodic intervals, 4 mL aliquots of the mixed solutions were collected and centrifuged immediately to remove photocatalyst particles prior to analysis, and the concentration of the pollutant was measured by UV-Vis spectrometry at the respective characteristics wavelength for each pollutant. 22 For the recycling experiments, the photocatalysts were collected via filtration and washed with deionized water and ethanol to remove the residual pollutants and dried under vacuum at 60 °C overnight, and fresh pollutant solution, and H 2 O 2 , were used for the next run.…”

Recent advances in the Biosynthesis of Zirconium Oxide Nanoparticles and their Biological Applications

“…Zirconia was synthesized through various methods like ball-mill assisted, ultrasonic abetted, sol-gel, electrical arc-based discharge 11 , precipitation 12 , hydrothermal 13 , heat plasma path 14 , solvothermal 15 , explosive emulsion 16 , microwave-assisted 17 , and electrochemical deposition 18 . However, these artificial approaches necessitate high temperature and pressures, a more extended reaction period, expensive and hazardous chemical forerunners, and the use of specialized tools for investigational work, all of which have a detrimental environmental impact 19 .…”

Structure, magnetic, and photocatalysis of La0.7Sr0.3MO3 (M = Mn, Co, and Fe) perovskite nanoparticles: Novel photocatalytic materials

“…Several metal oxide nanosized semiconductor nanoparticles have been used in different applications, including dye solution photodegradation and contaminated water. The predominant research in the photocatalysis field for wastewater purification has included semiconductors of wide bandgap and high surface-to-volume ratio material such as titanium dioxide (TiO 2 ), zinc oxide (ZnO), tin oxide (SnO 2 ), and zirconium oxide (ZrO 2 ) (Anandan et al 2020 ). This compound is called the hole-doped.…”
