Supported cobalt-promoted platinum bimetallic nanoparticles – a thermal study
Abstract: The Co-promoted Pt-based bimetallic catalysts were prepared using surface organometallic method (SOMC), to obtain catalysts with cobalt to platinum surface atomic ratio of 1:2 and 1:1. Temperature-programmed reduction (TPR) profiles showed two distinct temperature regions for hydrogen uptake both by the parent 5% Pt/Al2O3 and the Co-promoted catalysts. The shift in peak maxima in the case of promoted catalysts to higher temperatures has been interpreted as a result of formation …
