摘要: Bimetallic Ru-Cu catalysts supported on SiO2, α-Al2O3, γ-Al2O3 have been prepared using precursors which do not contain chlorine and characterized by CO chemisorption TPR. Catalytic activity has tested in the propane hydrogenolysis. It observed that degree of formation bimetallic aggregates depends support used. is suggested interaction between Ru Cu strongly influenced strength metal-support interaction.
