In addition, Pt/La<SUB>9.33</SUB>Si<SUB>6</SUB>O<SUB>26</SUB> catalyst exhibited higher activity for selective catalytic reduction of NO than Pt/Al<SUB>2</SUB>O<SUB>3</SUB> catalyst. Substitution of Ba<SUP>2+</SUP> for La<SUP>3+</SUP> of La<SUB>9.33</SUB>Si<SUB>6</SUB>O<SUB>26</SUB> led to increased catalytic activity at low temperature.",
