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 degrees C, 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 degrees C to be 0.36 mmol Cl/g(cat), while on Ru/Al2O3, the value is 1.46 mmol Cl/g(cat). (C) 2013 Elsevier B.V. All rights reserved.
