Abstract

The surface of the catalyst, Ln2Ti2O7 where Ln=Y, Sm, Gd and Tb was analysed by X-ray photoelectron spectroscopy. Terbium is found to be present in 3+ and 4+ states while Y, Sm and Gd are present in the 3+ state. The catalytic activity of these oxides was tested using decomposition of N2O as the test reaction and the catalytic activity was correlated to the surface properties.
