Improving the reducibility of CeO2/TiO2 by high-temperature redox treatment: the key role of atomically thin CeO2 surface layers

Redox properties on CeO 2 /TiO 2 system are reversibly modified with SRMO and SRSO treatments. The single low temperature peak featuring on SRMO samples is coming from a highly dispersed ceria thin layer extended over the TiO 2 surface.
