Pt-CoOx nanoparticles supported on ETS-10 for preferential oxidation of CO reaction

In this paper we prepare bimetallic Pt-CoOx nanoparticles which are further supported in microporous titanosilicate ETS-10. This support has been previously demonstrated as a good candidate for this reaction in the presence of CO2 and H2O. The bimetallic nanoparticles and the supported catalysts con...
