Single-phase La9.33Si6O26 and La8.33ASi6O25.5 (A = Ca, Sr, Ba) were obtained by a sol-gel method. Pd/La9.33Si6O26 catalyst exhibited high activity for oxidation of C3H6, comparable to Pd/Al2O3 catalyst, although the specific surface area of La9.33Si6O26 was lower than that of Al2O3. In addition, Pt/La9.33Si6O26 catalyst exhibited higher activity for selective catalytic reduction of NO than Pt/Al2O3 catalyst. Substitution of Ba2+ for La3+ of La9.33Si6O26 led to increased catalytic activity at low temperature.", pages = "703-708(6)", url = "http://www.ingentaconnect.com/content/vsp/rci/2008/00000034/F0020008/art00007" doi = "doi:10.1163/156856708786189410" }
