Ca doped CuScO2 (CSO) delafossite oxides of 3-4 μm were synthesized through the hydrothermal method using Cu(NO3)2·3H2O, Sc(NO3)3·xH2O as the precursor at 240 °C for 24 h in this work. The influence of the process parameters (reaction temperature, Cu/Sc molar ratios, EG (ethylene glycol) quantity, NaOH mineralizer, reactant concentration) on the structure and morphology of CSO was studied systematically. The crystal structure, morphology, and chemical composition of these Ca doped CSO (0, 1 at%, 3 at%, and 5 at%) sheets were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS).
