【 摘 要 】

Cerium based-compounds have great importancein a wide range of technological applications, such as: fuel cell devices development;metallurgic processes, petroleum refining; glass and ceramic production. Recently,its catalytic properties have been also explored for environmental applications,especially those to prevent or to control atmospheric and water pollution. Subjectscovered in this work include a brief description of the fundaments of ceriumcatalytic properties and some relevant technological applications. Special attentionis given to its photocatalytic activity and its ability to degrade pollutants.Recent results and future prospect about these applications are also evaluated.
