Importance of Nano clusters of Copper sulfides (CuS) is well known due to its interesting properties. Our group have studied nanoalloy clusters of (CuS)n; (n = 1–8) in terms of Conceptual Density Functional Theory (CDFT) based descriptors, aiming to explore its electronic and other properties. Global DFT based descriptors have been computed for ground state configurations and low-lying isomers of (CuS)n clusters. Our computed HOMO-LUMO energy difference, lying in the range of 1.25–3.53 eV, indicate possibility of utilization of (CuS) n clusters as renewable energy sources specially in photocatalysis and solar cell applications. A statistical regression analysis has been made between electronic and photo-catalytic properties of copper-sulfide clusters with their computational counterparts. The close agreement between experimental and computed data strengthens our analytical approach.
