ChemInform Abstract: Study of Acidic Titania/Silica Mixed Oxides and Their Use as Supports for Nickel Catalysts.
Abstract
Amorphous TiO2/SiO2 mixed oxides, containing 25-75 wt.% TiO2 are prepared by coprecipitation and subsequent calcination at 773 K. The calcined oxide mixture is found to be more acidic and to have a higher activity for 1-butene isomerization than either of the pure components.
ChemInform Abstract
Amorphous TiO2/SiO2 mixed oxides, containing 25-75 wt.% TiO2 are prepared by coprecipitation and subsequent calcination at 773 K. The calcined oxide mixture is found to be more acidic and to have a higher activity for 1-butene isomerization than either of the pure components. After reduction at 773 K, Ni catalysts supported on the mixed oxides exhibit support effects in the form of suppressions inhydrogen chemisorption and ethane hydrogenolysis. The behavior of these catalysts differs from that expected for a strong metal-support interaction system.
