ZFDT powders effectively photodegraded methyl orange under visible light irradiation and achieved maximum photoactivity when the amount of zinc ferrite was 1.5%.
Showed high efficiency when compared to TiO2 photocatalyst for photoreduction of water to hydrogen in the visible light range with the combination of Co2+, TiO2 and heteropoly acid.
The colloidal TiO2 nanoparticles treated with triethylamine by a batch system was found to show particularly efficient photocatalytic activity under visible illumination.
The 1% NiO/InVO4 catalyst which was reduced at 500°C and oxidized at ambient condition for 48 h gave the highest activity with a rate of 896 μmol h−1 g−1.
