Abstract/Summary

This research is subdivided into two parts (Part 1: Photocatalytic degradation of Bisphenol A using graphitic carbon nitride/ silver phosphate (g-C3N4)/ Ag3PO4) hybrid photocatalyst under visible LED light irradiation and Part 2 : Sonochemical synthesis, characterization and photocatalytic properties of hydroxyapatite nano-rods derived from mussel shells.) In Part 1, the hybrid photocatalyst (g-C3N4/ Ag3PO4) was synthesized using simple in-situ precipitation method. The hybrid (g-C3N4/ Ag3PO4) photocatalyst was characterized by x-ray diffraction (XRD), scanning electron microscopy-energy Dispersive X-ray (SEM-EDX) and fourier transform infrared spectroscopy (FT-IR). The photodegradation of Bisphenol A using (g-C3N4/ Ag3PO4) photocatalyst was studied considering the effects of different parameters such as percentage loading of Ag3PO4, catalyst loading and radical scavengers. In Part 2, sonochemical synthesis of hydroxyapatite (HAp) nano-rods derived from mussel shells was reported. HAp nano-rods were characterized by XRD, SEM-EDX, Transmission Electron Microscopy (TEM) and FT-IR. The photocatalytic activity of HAp nano-rods was investigated using Rhodamine B (dye) for the first time. The results confirm that degradation efficiency of 86.8% for RhB was observed after 300 min in the presence of HAp nano-rods photocatalyst.
