Abstract
The chemical transformations of CeO2 and Ru/CeO2 catalysts under oxidative treatment (i.e., typical conditions of oxidation reactions on metal/oxide catalysts) were investigated using in situ Raman spectroscopy, and complemented by near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS). The main attention was focused on the Raman study of the effect of Ru loadinag degree on the structure of CeO2 support in Ru/CeO2 catalysts undergoing oxidative treatment. The advances and limitations of Raman spectroscopy for studying the chemical state of Ru/CeO2 catalysts were systematically investigated and discussed, demonstrating its high potential to monitoring the physicochemical state of ceria support in the Ru/CeO2 system. The limited applicability of Raman spectroscopy for monitoring the Ru species in Ru/CeO2 catalyst was also demonstrated.
期刊介绍：
The journal Crystal Research and Technology is a pure online Journal (since 2012).
Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of
-crystal growth techniques and phenomena (including bulk growth, thin films)
-modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals)
-industrial crystallisation
-application of crystals in materials science, electronics, data storage, and optics
-experimental, simulation and theoretical studies of the structural properties of crystals
-crystallographic computing
