Photocatalytic degradation of methylene blue and Rhodamine B using polythiophene nanocomposites under visible and UV light

Abstract

Polythiophene/ Aluminium oxide (PA) nanocomposite is prepared using in-situ chemical polymerization method using camphor sulfonic acid as surfactant. The prepared samples were characterized using a UV-Visible spectrophotometer which shows a band gap of 3.64 and 3.80 eV for pure PTH and PA nanocomposite respectively. The photocatalytic activity of PA nanocomposite enhances the photocatalytic degradation of Methylene blue (MB) and Rhodamine B (RhB) dye under visible and UV light illuminations than the pure PTH.Polythiophene/ Aluminium oxide (PA) nanocomposite is prepared using in-situ chemical polymerization method using camphor sulfonic acid as surfactant.
