摘要: Abstract Ru-Cu/MgO catalysts, prepared using Ru(NO)(NO 3 ) as ruthenium precursor, have been investigated in the hydrogenolysis of propane. Samples characterized by CO chemisorption and temperature-programmed reduction.On increasing amount Cu catalytic activity initially decreases, reaching a minimum at about 20 at.% Cu, then remains constant higher contents. A comparison with similar samples from RuCl shows different behaviour function content. It is suggested that reduction temperature precursors, therefore rate formation growth metal crystallites, plays an important role determining degree Ru-Cu interaction.
