Description générale

Cerium (III) nitrate hexahydrate is a white-to-yellowcrystalline salt, which is hygroscopic and air-sensitive. Cerium (III) nitratehexahydrate is highly soluble in water, alcohol, and acetone. Cerium (III)nitrate hexahydrate melts at 57 °C and begins to thermally decompose at190 °Cwith complete decomposition to the oxide by 400 °C.

Application

Cerium (III) nitrate hexahydrate is widely used as a sourceof cerium, especially in the synthesis of micro- or nano-structured ceria(cerium oxide). Researchers leverage the high solubility and low decompositiontemperature of cerium (III) nitrate hexahydrate in hydrothermal reactions,sol-gel processing, and co-precipitation/calcination reactions to synthesizeceria and cerium-compounds. For example, for one study materials scientistsprepared a two-dimensional cobalt-doped ceria nanosheet by co-precipitating andcalcining cerium nitrate and cobalt acetate. As another example, researchersused the high solubility of cerium nitrate to grow crystals of two-dimensionalrare-earth double perovskites. Researchers have also used cerium nitrate to formcomposites, such as graphene-ceria nanoparticle composites and TiO2/CeO2nanocomposites, utilizing cerium’s (III/IV) redox chemistry forlight-absorption and photocatalysis. One example, that shows the maturematerials engineering of cerium (III) nitrate chemistry, is a study that uses acalcium-doped cerium nanotube composite with lithiumbis(trifluoromethanesulfonyl)imide (LiTFSI) poly(ethylene oxide) for asolid-state lithium-ion electrolyte. The Ca-CeO2 nanotubes, which achievehigher concentrations of oxygen vacancies than undoped CeO2, were made byelectrospinning from a solution of cerium nitrate and calcium nitrate withpolyvinylpyrrolidone, which is removed by pyrolysis in a final calcination.

The Rare Earth Crisis—The Supply/Demand Situation for 2010–2015

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.
