Platinum-germanium catalysts supported on a non-acidic Al2O3 have been prepared by adding Ge in amounts corresponding nominally to 1/8 (PtGe1/8/Al2O3); 1/2 (PtGe1/2/Al2O3); 1 (PtGe1/Al2O3) and 2 (PtGe2/Al2O3) monolayers by controlled surface reaction of Ge(n-C4H9)4 to Pt/Al2O3. These catalysts were characterized by electron microscopy (TEM), FTIR of CO adsorption and H2 chemisorption. The ring opening...
