Abstract
Deterioration of water resources and increased levels of water pollution have become two major factors that threaten the fundamental balance of ecosystems. Owed to their destructive impact, the concern to regulate and remediate them has amplified in the recent past. Herein we presently propose a simple hydrothermal strategy for synthesizing iron phosphate, FePO4 (FP) nanoparticles. Their ability as a photocatalyst material for photocatalytically degrading Reactive Black 5, Red 198 and Yellow 145 dyes was examined and found to be 95.74, 90.32 and 87.65%, respectively. The dependency of photocatalysis process on dye concentration and pH was explored to enlighten the possible variations that might occur during practical applications. Furthermore, the kinetic pathway in which the photocatalysis takes place was also verified to fall under pseudo-first order kinetics. Recyclability/reusability parameter was also studied to elaborate on its optimum efficiency when the photocatalyst is used repeatedly. In conclusion, the synthesized FP photocatalyst is demonstrated to act as a promising material for superior photocatalytic degradation of dyes in wastewater effluents.
