Evolution of Hierarchical Hexagonal Stacked Plates of CuS from Liquid-Liquid Interface and its Photocatalytic Application for Oxidative Degradation of Different Dyes under Indoor Lighting

Blue solution of copper(II) acetylacetonate complex, [Cu(acac)(2)] in dichloromethane (DCM) and an aqueous alkaline solution of thioacetamide (TAA) constitute a biphasic system The system in a screw cap test tube under a modified hydrothermal (MHT) reaction condition produces a greenish black solid at the liquid liquid interface It has been characterized that the solid mass is an assembly of hexagonal copper sulfide (CuS) nanoplates representing a hierarchical structure The as-synthesized CuS nanoplates are well characterized by several physical techniques An ethanolic dispersion of CuS presents a high band gap energy (2.2 eV) which assists visible light photocatalytic mineralization of different dye molecules Thus a cleanup measure of dye contaminated water body even under indoor light comes true
