Template‐assisted Morphological Evolution of Cu2S and Cu2MoS4 from Octahedral Cu2O Crystals

Various morphologies of Cu 2 S and Cu 2 MoS 4 were synthesized from an octahedral Cu 2 O template in the presence of various concentrations of sodium molybdate and thioacetamide by carrying out solvothermal reactions in an ethylene glycol solvent. The morphology varied from hollow octahedral Cu 2 S structures, through small pieces of P‐Cu 2 MoS 4 , and finally to thin square‐like plates of I‐Cu 2 MoS 4 , depending on the concentrations of sodium molybdate and thioacetamide. The XRD data indicated that the Cu 2 MoS 4 structural phases changed from P 2m to I 2 m the concentrations of sodium molybdate and thioacetamide increased.
