Large-scale synthesis of CuS hexaplates in mixed solvents using a solvothermal method
Large-scale covellite CuS hexaplates were successfully synthesized by the 200 °C solvothermal reactions of CuCl2.2H2O and (NH4)2S in C2H5OH-H2O mixed solvents containing HCOOH as a pH stabilizer, including different amounts and molecular weights (MWs) of polyethylene glycol (PEG). By using XRD and S...
