Abstract

Supported metallic catalysts were prepared from pyrolysis of the organometallic clusters RuOs₃(CO)₁₃(μ-H)₂, Os₃(CO)₁₀(μ-AuPPh₃)₂, Os₃(CO)₁₂, Ru₃(CO)₁₂ and [Ru(CO)₄]_n, on either silica or titania, and their catalytic performance for CO oxidation has been assessed against a supported catalyst prepared from RuCl₃. Ruthenium catalysts prepared from organometallic precursors were found to exhibit better activity, and that supported on TiO₂ exhibited activity at the lowest operating temperature.
