Formation of Molecular Chlorine by the Decomposition of 1, 2-Dichloroethane over Ru Supported on Titania-Silica

Abstract

Decomposition of 1, 2-dichloroethane was examined over Ru, Rh, Pd, Pt, Cu, and Cr catalysts supported on TiO₂-SiO₂ in air. A large amount of Cl₂ was formed over Ru/TiO₂-SiO₂ catalyst at 400°C, whereas Rh, Pd, and Pt catalysts did not produce Cl₂ even at 450°C. Although Cu and Cr catalysts also produced Cl₂ effectively, the maximum activity observed at 650°C was still lower than that of Ru at 400°C.
