A magnetic palladium nickel carbon (Fe3O4@Pd@Ni/C) nanocomposite has been synthesized using a simple one-pot procedure via a hydrothermal approach. Ferric nitrate, palladium acetate, and nickel nitrate were dissolved in water together with glucose, and the mixture was heated in an autoclave. The Fe3O4@Pd@Ni/C nanocomposite was characterized via XRD, TEM, FE-SEM, VSM, EDS, and XPS studies. The catalytic
磁性钯镍碳(Fe 3 O 4 @Pd@Ni/C)纳米复合材料已通过水热法使用简单的一锅法合成。将硝酸铁、醋酸钯和硝酸镍与葡萄糖一起溶解在水中,并将混合物在高压釜中加热。Fe 3 O 4 @Pd@Ni/C 纳米复合材料通过XRD、TEM、FE-SEM、VSM、EDS 和 XPS 研究进行表征。Fe 3 O 4的催化能力研究了@Pd@Ni/C 纳米复合材料用于合成二苯乙烯基苯和 9,10-二苯乙烯基蒽衍生物。该方法显示出明显的优点,如催化剂的可回收性、实验操作简单、收率良好至极好等。
Understanding the Unconventional Effects of Halogenation on the Luminescent Properties of Oligo(Phenylene Vinylene) Molecules
It is commonly known that halogenation tends to decrease the luminescence quantum yield of an organic dye, owing to the high electronegativity and heavy‐atom effect of the halogen atom. However, based on an investigation of the effects of halogenation on the luminescence of the oligo(phenylenevinylene) (OPV) framework, we demonstrate that halogenation can have positive impact on the solid‐state fluorescence
