Copper-based chalcogenides of earth-abundant elements have recently arisen as alternate materials for solar energy conversion.Cu2MSnS4(M=Zn,Fe),a class of quate
Ternary catalysts,namely CuO-CoOx-CeO2,are prepared by coprecipitation with different pH and characterized by techniques such as N2 adsorption/desorption,XRD,TP
