摘要

在- 80 ~ 305℃的温度范围内，用程序升温还原法(TPR)研究了PdCl2在低聚芳烃上的还原模式。确定了低聚物基质的化学组成和Pd负载的影响。一种特殊的金属-载体相互作用极大地影响了Pd的还原性，使其在氧化形式(即Pd2+)下稳定下来。

Palladium-based catalysts supported on oligomeric aramides. A TPR investigation

The reduction pattern of PdCl₂ supported on oligomeric aramides has been investigated by temperature programmed reduction (TPR) measurements in the range of temperature −80 to 305°C. The influence both of chemical composition of the oligomeric matrix and Pd loading has been ascertained. A peculiar metal—support interaction greatly affects the reducibility of Pd, allowing its stabilisation in the oxidised form (i.e., Pd²⁺).

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.
