摘要
The use of mixed magnesium oxo-fluoride support, obtained by one-step sol-gel method, for iridium active phase allowed obtaining new catalysts of high activities in the hydrogenation of toluene. The Ir/MgF2-MgO catalyst was a hundred times more active than that of the iridium system supported on MgF2. The effect of the MgO content and catalyst pre-treatment conditions appeared to have a clear influence on the activity of tested iridium catalysts. The highest activity, expressed as TOF, s(-1) was obtained for the catalyst activated at 500 degrees C supported on magnesium oxo-fluoride containing 60 mol.% MgO. (C) 2011 Elsevier B.V.
