NiSe2/Ag3PO4 Nanocomposites for Enhanced Visible Light Photocatalysts for Environmental Remediation Applications

This study investigated the use of NiSe2/Ag3PO4 nanocomposite catalysts for photocatalytic degradation RhB and BPA pollutants. Samples pure NiSe2, Ag3PO4, composites with varying NiSe2 (10%, 20%, 30%) proportions were synthesized using hydrothermal techniques. The 20% composite showed greatest efficiency both degradation. also examined impact various factors, such as initial concentration dye, catalyst amount, pH, reaction time, on photodegradation process. effectively degraded 10 ppm in 20 min 30 min. physical properties samples SEM, PXRD, energy-dispersive X-ray spectroscopy. cycling runs exhibited improved stability compared to a rate 99% BPA. combination synergistic effect Ag3PO4 played vital role enhancing photocatalysts. Both followed pseudo-first-order kinetic models constants 0.1266 min−1 0.2275 min−1, respectively. presented Z-scheme mechanism elucidate process by after active species capture experiments, which that superoxide anion radicals holes responsible photodegradation.
