Ru/TiO₂ and Ru/Al₂O₃ were prepared by wet impregnation of TiO₂ and Al₂O₃, and tested in the catalytic decomposition of dichloromethane (DCM). Ru/TiO₂ catalyst presents the higher activity than Ru/Al₂O₃ catalyst, with 50 % and 90 % conversion occurring at 235 and 267 ¡ãC, respectively. Moreover, the higher stability on Ru/TiO₂ catalyst is observed, which can be related to ready removal of Cl species produced during DCM decomposition. The chlorine uptake on Ru/TiO₂ catalyst is estimated at 240 ¡ãC to be 0.36 mmol Cl/g_cat, while on Ru/Al₂O₃, the value is 1.46 mmol Cl/g_cat.
