Surface characterization and catalytic activity of Ln2Ti2O7 (Ln = Y, Sm, Gd and Tb)

Surface characterization and catalytic activity of Ln2Ti2O7 (Ln = Y, Sm, Gd and Tb)

An attempt was made to correlate the catalytic activity of these titanates with surface properties. Catalytic activity was tested using decomposition of N2O as the test reaction. Terbium is found to be present in 3+ and 4+ states while Y, Sm and Gd are present in the 3+ state, as established by X-ra...
