Sonochemical synthesis of CZTS photocatalyst for photocatalytic degradation of phthalic acid

Year: 2019

Type: article

Abstract: In recent year, sonochemistry has fascinated some interest in the fabrication of nanostructured materials and functional nanoparticles because the chemical activity of ultrasound may cause different effects such as the generation of heat, mass transfer or intimate contact between materials, distribution of contaminated layers of chemicals and generation of free chemical radicals. In this work, Cu 2 ZnSnS 4 (CZTS) photocatalyst is prepared by simple, cost effective, sonochemical method and used for photocatalytic degradation of phthalic acid. The ultrasonic treatment affects the structural, morphological, optical, contact angle properties of CZTS photocatalyst. The XRD and FT-Raman spectroscopy study shows the formation of a single phase CZTS with kesterite structure. SEM analysis reveals nano-spherical architecture with pinhole and crake free surface. The optical study shows that band gap energy lies in the visible region of the solar spectrum and useful for visible light assisted photocatalysis. The end results show that the CZTS photocatalyst exhibited about 56% degradation of phthalic acid under sunlight illumination. The mineralization study of phthalic acid is done by determining chemical oxygen demand (COD) values.
