Preparation, Characterization and Catalytic Properties of CuCl14PC/Y Nano-Composite
|
Abstract:
Well-crystallized CuCl14PC/zeolite Y nano-composite of average particle size about 60nm (denoted as CuCl14PC/nano-Y) was successfully synthesized via zeolite synthesis method. The integrity of the nano-zeolite host was confirmed by XRD and TEM. The CuCl14PC complexes entrapped in the nano-hosts were characterized by XRD, TEM, FTIR, TG/DTA, ICP, and UV-vis. CuCl14PC/Y samples with different particle sizes in micro-scale were also synthesized by adjusting the temperature and water content. CuCl14PC in nano-Y exhibits the catalytic activity 3.1 times higher than CuCl14PC in normal Y with particle size of 550nm for the liquid phase oxidation of cyclohexane with aqueous H2O2 due to bigger surface areas and shorter diffusion pathways.
