Investigation of the photocatalytic capabilities of green-synthesized CeO2–ZnO nanocomposites for degrading acid orange 7 dye under sunlight

This study investigates the production and photocatalytic activity of CeO 2 –ZnO nanocomposites, synthesized for the first time using Bacopa monnieri leaf extract to degrade the Acid Orange 7 Dye (AO7). The nanocomposites were successfully prepared using an extract from Bacopa monnieri leaves as a sustainable r...

Visible light-assisted photocatalytic degradation kinetics of methylene blue (MB) dye by β-MoO3 nanoplates and α-MoO3 nanorods

In this study, α-MoO3 and β-MoO3 photocatalysts were synthesized using an ultrasonic-assisted hydrothermal method and annealed in air at 450 °C and 650 °C. The physicochemical properties of the catalysts were investigated using X-ray diffraction (XRD), Fourier-transformed infrared spectroscopy (FT-IR), field emission-s...
