Synthesis of Cobalt Sulfide and Cobalt-Iron Sulfide from Cobalt (III) Dithiocarbamate Complexes and Their Utility for Photocatalytic Degradation of Dyes

Abstract

Tris(N-(pyrrol-2-ylmethyl)-N-butyldithiocarbamato-S, S′) cobalt(III) (1), bis(N-methylferrocenyl-N-(2-phenylethyl) dithiocarbamato-S, S′) nickel(II) (2) complexes were used as single source precursors for the preparation of cobalt sulfide and cobalt-iron sulfide nanoparticles. IR spectral studies on nanoparticles confirm the presence of capping agent (triethylenetetramine). The nanoparticles are explored as photocatalysts to study the degradation of dyes using methylene blue and rhodamine-B in aqueous solution under UV irradiation. The cobalt-iron sulfide works as an efficient photocatalyst for degradation of rhodamine-B..
