Subnanometer nickel clusters in complex reducing agents
Nickel-based, complex reducing agent (NiCRA) prepared by reacting Ni(OAc)2, NaH and t-BuONa in THF were studied by transmission electron microscopy. Nickel is in the form of 1 nm-large clusters. In presence of bipyridyl ligands particles as small as 0.5 nm are detected. The formation and stability of nickel clusters is attributed to the strong reducing potential of the NaH—t-BuONa mixture complexing the nickel clusters. Bipyridyl ligands exert an additional stabilization so that clusters containing less than 10 atoms could be present.
期刊介绍：
Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes.
The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
