Simple Hydrothermal Method

A mesoporous La2Sn2O7-HT pyrochlore with an unusually high surface area was successfully synthesized with a simple hydrothermal method at 200 °C. Due to its high surface area and the presence of more active oxygen species, Pd supported on this mesoporous La2Sn2O7-HT shows remarkable CO oxidation activity.
