Abstract

Electron paramagnetic resonance (EPR) spectroscopy was applied to study structure–performance relationships for copper-containing catalysts based on Al-Zr-Ce mixed oxides with various oxide support synthesis temperature. In situ EPR showed that the state of Cu²⁺ sites depends on the phase composition of the support, temperature, as well as the presence of the reaction medium during catalysis.

Cu/Al-Zr-Ce乙醇脱氢催化剂的EPR表征:活性位点开发和焦化控制

应用电子顺磁共振（EPR）谱研究了不同氧化物载体合成温度下基于Al-Zr-Ce混合氧化物的含铜催化剂的结构-性能关系。原位EPR表明，Cu2+位点的状态取决于载体的相组成、温度以及催化过程中反应介质的存在。

期刊介绍： MRC is devoted to the rapid publication of papers which are concerned with the development of magnetic resonance techniques, or in which the application of such techniques plays a pivotal part. Contributions from scientists working in all areas of NMR, ESR and NQR are invited, and papers describing applications in all branches of chemistry, structural biology and materials chemistry are published. The journal is of particular interest not only to scientists working in academic research, but also those working in commercial organisations who need to keep up-to-date with the latest practical applications of magnetic resonance techniques.
