Abstract: The photocatalytic efficiency of Cu (4 wt%) and varied Fe concentrations (2, 3, 4 and 8 wt%) doped ZnO nanoparticles (2FCZ, 3FCZ, 4FCZ, and 8FCZ) was investigated for the photocatalytic degradation of different types of dyes such as MB, RhB, RB, BY, and AR by using an artificial photoreactor and under natural sunlight. [Display omitted] • FCZ nanocatalyst were studied for the degradation of MB, RhB, RB, BY and AR. • Artificial reactor is a simple practical set up for in-house dye degradation. • FCZs are efficient photocatalyst in both artificial reactor and natural sunlight. • 1 mL H 2 O 2 and 1 mg catalyst sufficient for both individual and binary mixture of dyes. • This approach provides a new insight into treating textile wastewater. The objective of this work was to utilize Zinc Oxide (ZnO) nanoparticles doped with 4 wt% Cu and varying concentrations of Fe (2, 3, 4, and 8 wt%) as efficient photocatalysts for dye degradation. The synthesized 2FCZ, 3FCZ, 4FCZ, and 8FCZ nanoparticles were tested on various dyes (Methylene Blue (MB), Rhodamine B (RhB), Rose Bengal (RB), Brilliant Yellow (BY), Acid Red (AR)) and their binary mixtures under artificial light and sunlight. Using 1 mg of catalyst and 1 mL of H 2 O 2 for 100 mL of 10 ppm dye solution, 4FCZ showed the highest degradation efficiency. In an artificial reactor, it achieved 98.1 %, 94.8 %, 48 %, 65.6 %, and 21 % for the respective dyes, and in sunlight, 88.7 %, 75.3 %, 78.7 %, 52 %, and 27 %. 4FCZ demonstrated better performance in the artificial photoreactor. The catalyst's selectivity was confirmed using binary dye mixtures, and its efficiency was attributed to the generation of OH radicals and inhibition of e−/h+ recombination. A key advantage is the minimal catalyst and H 2 O 2 required, making this method promising for large-scale wastewater treatment, particularly in the textile industry. [ABSTRACT FROM AUTHOR]
