Resumen: 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 containing different loadings of nanoparticles have been extensively characterized and tested in the PROX reaction. The characterization of the nanoparticles discarded the formation of a metallic alloy, although Co and Pt are intimately in contact in the nanoparticle as the HAADF-STEM images revealed. XPS confirmed that the calcined nanoparticles would consist of metallic platinum and cobalt and Pt oxides. The catalyst containing 1.4 wt.% of PtCo nanoparticles can achieve complete CO conversion in the temperature range 120–150 °C working at WHSV = 30 L h-1 g-1.
