摘要: 用沸石合成法制备了CuCl14Pc/Y分子筛纳米复合材料(简称为CuCl14Pc/nano-Y),考察了合成条件对纳米复合材料的粒度影响.用XRD、ICP、TG-DTA、TEM、FTIR、UV-vis及催化反应等对其性能作了表征.结果表明:铜酞菁(CuCl14Pc)经过水热晶化后,部分被分装在纳米Y型分子筛的空腔中,其催化氧化性能较普通CuCl14Pc/Y分子筛复合材料有很大提高.

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.

Key words: CuCl14PC, zeolite, nanocrystalline, cyclohexane oxidation
