摘要: The effect of multivalent cations, Ca2+, Ba2+, Y3+, Ce3+ and La3+ on the agglomeration Ru clusters NaY zeolite under oxygen at high temperature has been investigated with 129Xe NMR spectroscopy X-ray absorption fine structure. Multivalent metal cations exchanged into suppress neither migration nor small inside supercage large particles onto external surface 1 atm above 520 K. However, resultant particle size depends type zeolite.
