Preparation of different morphology Cu/GO nanocomposites and their catalytic performance for thermal decomposition of ammonium perchlorate.

Cu nanoparticles are more active catalytically than CuO nanoparticles, which have been widely studied as catalysts for organic synthesis, electrochemistry, and optics. However, Cu nanoparticles are easily agglomerated and oxidized in air. In this research, columnar, flower-like, bubble-like and teardrop-shaped Cu/GO nanocomposites were fabricated a water-solvent thermal method and high temperature calcination technique using deionized water (HO), methanol (CHOH), ethanol (CHCHOH) and ethylene glycol (EG) as the solvent, respectively.
