SYNTHESIS OF POLYANILINE-BASED CATALYSTS: PHOTOCATALYTIC DEGRADATION OF METHYLENE BLUE

Abstract

The increasing use of dyes in various industries has raised concerns regarding the potential release of harmful substances into the environment and their influence on human health. The incorporating style of polyaniline-based catalysts has attracted great interest in the field of photocatalysis, specifically for dye degradation from water. Polyaniline CuO (PANI-CuO) catalysts with varying PANI/CuO mole ratios (1:8, 1:1, and 8:1) were synthesized by in-situ chemical oxidation polymerization (PCI) and mechano-chemical preparation (PCS) methods. FTIR, XRD, and SEM analyses confirmed the presence of CuO and PANI in PCS catalysts. However, CuO particles were not detected in PCI specimens due to the dissolution of CuO in a highly acidic medium. The photocatalytic efficiency of prepared two different series of PANI-CuO catalysts was assessed by the degradation of methylene blue (MB) dye degradation for comparative purposes. The results implied that the preparation process significantly concerns the photocatalytic performance with PCI catalysts exhibiting higher MB photocatalytic degradation than PCS specimens. The PCI-18 specimen achieved 56% degradation of MB in 300 minutes.
