Metallic osmium and ruthenium nanoparticles for CO oxidation
چکیده انگلیسی

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.

A metallic ruthenium catalyst, supported on TiO2, prepared from the organometallic precursor [Ru(CO)4]n exhibits activity for CO oxidation at ∼150 °C lower operating temperature than a supported catalyst prepared from RuCl3.Figure optionsDownload as PowerPoint slide
