Synthesis, Structural Elucidation and Photocatalytic Studies of Some 4- Aminoantipyrine Based Ruthenium (III) Complexes

Photo catalytic studies are considered as the effective process of organic pollutants degradation, which decrease the impacts on human health and the environment. The present study was conducted to evaluate the photo catalytic activities of some 4-aminoantipyrine based Ru(III) complexes against methylene blue dye. A series of five novel Schiff base ruthenium complexes (RuL2Cl2) have been synthesized by the reaction between five types of 4-aminoantipyrine derived Schiff base ligands and ruthenium trichloride by direct condensation method. The synthesized ligands and metal complexes were characterized using analytical and various spectral techniques. UV-light is used to calculate the rate of photo catalytic degradation of methylene blue using above mentioned metal complexes. Increase in the amount of catalyst, increases the degradation because it increases the number of active sites on the catalysts surface. Furthermore increase may cause the accumulation of free catalyst and also increase the opacity and decreases UV light penetration. The formation of hydroxyl radicals are the cause for successful degradation of methylene blue dye. The synthesized Ru(III) complexes show highest percentage of degradation on photo catalytic activity.
