Mesoporous Silica-Lanthanum: Characterization and Catalytic Activity on NO Reduction
A series of ordered mesoporous silica-lanthanum materials was prepared. The influence of lanthanum into a silica matrix on the structural, textural and acidic properties is described. The mechanical and hydrothermal stability of mesoporous materials were evaluated. The catalytic activity of cobalt catalyst for selective reduction of nitrogen oxide -in the presence of propane- at temperatures between 350 and 550 °C, was tested. A selective reduction of NO by cobalt-based catalyst raised 18 %, at 450 °C.
