Temperature-Programmed Reduction Studies on Fe-promoted Pt/Al2O3 Bimetallic Catalysts
Abstract: Pt/Al2O3-based bimetallic catalysts were prepared using surface organometallic method (SOMC) to obtain catalysts with a nominal promoter to platinum surface atomic ratio of 1:2 and 1:1 (corresponding to typically 0.2–0.4 mass% of the promoting metals; here Fe). Temperature-programmed reduction (TPR) studies showed two distinct temperature regions of hydrogen uptake during reduction by the parent Pt/Al2O3 (5 mass%) and the Fe-promoted catalysts. The shift in peak maxima in the case of …

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 …

Role of Electron Donors in MgCl2 Supported Ziegler-Natta Catalysis: DFT Approach
Abstract: An insight into the nature of carbonate-based electron donors in high-activity MgCl2 supported Ziegler-Natta (Z-N) catalysts has been studied and compared with conventional phthalate and diether systems by employing density functional theory (DFT) calculations. In the catalyst activation (one of the important processes to produce the active catalyst sites), the conventional monometallic and recently characterized bimetallic (TiCl2(Et)–Cl–AlEt2) active site are studied in the presence/absence of electron donors. These active sites …
