04 Effect of Cl/Ni molar ratio on the catalytic conversion of polypropylene into Cu-Ni/C composites and their application in catalyzing "Click" reaction
关键字：Carbon materials, Catalysis, Composites, Polypropylene
A one-pot approach to prepare Cu–Ni/C heterogeneous composites by carbonization of polypropylene (PP) using combined catalysts of Ni2O3 and CuCl was proposed. TEM, SEM, TGA and Raman measurements were performed to investigate the effects of Cl/Ni molar ratios on the yield and morphology of the resultant carbon materials. The yield of carbon materials in Cu–Ni/C first increased and then decreased...
