SAXS and XPS Characterization of Ru/Alumina Catalyst Synthesized by Microwave Irradiation Technique

Article Preview

Abstract:

Ru/Al2O3 catalyst have been synthesized by using two different methods. The aim of the present work is to studythe surface fractal behavior and the formation of Ruthenium metal in the presence and absence of PVP by SAXS and XPS measurement, respectively. Both of Ru-based nanocatalyst supported on Alumina powder has been synthesized in ethylene glycol under microwave irradiation. The samples were also characterized by TEM and FESEM. Nanoparticles with an average diameter about 2 nm and narrow distribution of sizes were obtained. According to XPS results, formation of metal Ru (0) was observed in all samples. The oxides form of Ru in the samples was obviously due to interaction with the air. Furthermore, chlorine content in the systems was still detected.
