Photocatalytic Activity of Some Mixed Ligand Metal Complexes as Heterogeneous Catalyst for Degradation of Azo Dye

Abstract

A series of ternary mixed ligand complexes of Ni(II) metal having general molecular formula is [NiPClINAP)(aa)·2H₂O]; where PClINAP is sodium salt of p-chloroisonitrosoacetophenone and aa is a L-amino acids like alanine, valine, leucine, methionine and phenylalanine were prepared. These complexes were characterised by several physico-chemical techniques such as elemental analysis, molar conductance determination, magnetic susceptibility measurements, electronic absorption spectral studies, IR studies and TG-DTA analysis. The photocatalytic activity of the synthesized Ni(II) complexes were studied as a heterogeneous catalyst for degradation of Eriochrome black-T dye.
