Solvothermal Synthesis of Copper Nanoparticles Loaded on Multi-Wall Carbon Nanotubes As Catalyst For Thermal Decomposition of Ammonium Perchlorate

Copper nanoparticles were synthesized on multiwall carbon nanotubes, (cu)/(mwcnts), based on solvothermal method. the used reagents include mwcnts, cupric nitrate trihydrate (cu (no3)2.3h2o), diethylene glycol (deg), diethanol amine. characterization of cu/mwcnts nanoparticles was performed by techniques of fourier transform infrared spectroscopy (ftir), raman spectroscopy, x-ray diffraction spectroscopy (xrd), inductively coupled plasma (icp), differential scanning calorimeter (dsc), and field emission scanning electron microscopy (fe-sem).the results show that the surface of mwcnts is covered by cu nanoparticles, and the diameter of cu/mwcnts nanoparticles gets larger than that of mwcnts. furthermore, in the presence of cu/mwcnts composite particles, the synthesized cu/mwcnts showed 95% cu loaded on the mwcnts. the results showed that using 3 wt.-% cu/mwcnts nano catalyst lowered the decomposition temperature of ap by 121.76 °c. the total enthalpy, for this case, was 1384.46 j g -1. this work indicates that the catalytic performance of cu/mwcnts can be improved the thermal decomposition of ap.
