TLDR
In this article, a nano zeolite photocatalyst with cerium oxide photosensitizer over Zeo-NaX was used for the degradation of green dye with visible light irradiation (100 W tungsten lamp).
Abstract
Synthesis of zeolite NaX (Zeo-NaX) from coal fly ash and its development into a photocatalyst is a rarely studied current research field. The present work focuses on this field by using cerium oxide photosensitizer over Zeo-NaX. The ceria supported zeolite-NaX (CeO2/Zeo-NaX) was prepared by introducing nanosize CeO2 into Zeo-NaX framework through ion-exchange method. The prepared catalysts were characterized by FT-IR, XRD, SEM, EDX, BET Surface area, and DRS techniques. Photocatalytic degradation of brilliant green dye (BG; 10 ppm) over the synthesized photocatalyst was studied with visible light irradiation (100 W tungsten lamp). The effects of pH, dye concentration, and catalyst dosage were also studied on the degradation reaction of BG. By varying the pH, dye concentration, and catalyst dosage of the observed percentage of photocatalytic degradation of BG are (28-100 %), (80-94 %) and (77-94 %) respectively. Thus the present work established the development of nano zeolite photocatalyst with CeO2 photosensitizer.
