A Schiffbase has been prepared by the condensation of 4amino -3,5-dimercapto, 1,2,4-triazole with 2,4-diaminobenzaldehyde. The ligand has been used for complexation with Mn(II), Cu(II) and Zn(II) metal ions. The complexes have been characterized by their elemental analysis, molar conductivity, magnetic susceptibility, IR spectra and electronic spectra. The very low value of molar conductivity of complexes

Ni@Pd core-shellnanoparticles with a mean particle size of 8–9 nm were prepared by solvothermal reduction of bivalent nickel and palladium in oleylamine and trioctylphosphine. Subsequently, the first-ever deposition of Ni@Pd core-shellnanoparticles having different compositions on a metal-organicframework (MIL-101) was accomplished by wet impregnation in n-hexane. The Ni@Pd/MIL-101 materials were
通过在油胺和三辛基膦中溶剂热还原二价镍和钯,制备了平均粒径为 8-9 nm 的 Ni@Pd 核壳纳米粒子。随后,通过在正己烷中湿浸渍,首次在金属有机骨架(MIL-101)上沉积了具有不同成分的 Ni@Pd 核壳纳米粒子。Ni@Pd/MIL-101 材料通过粉末 X 射线衍射、傅里叶变换红外光谱、透射电子显微镜和能量色散 X 射线光谱进行表征,并在温和的反应条件下作为硝基苯加氢的催化剂进行了研究。在 30 °C 和 0.1 MPa 的 H2 压力下,Ni@Pd/MIL-101 为硝基苯加氢提供了高达 375 h-1 的 TOF,适用于广泛的取代硝基芳烃。
