【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．更多还原

【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.更多还原
