Description

General description

Cerium (III) nitrate hexahydrate is a widely used source of cerium in materials science. It is a white-to-yellow crystalline salt that is hygroscopic and air-sensitive. It is highly soluble in water, alcohol, and acetone, although solutions can appear slightly hazy. Like many trivalent metal nitrates, cerium (III) nitrate hexahydrate melts at a low temperature (57 °C)and thermally decomposes at low temperatures too, beginning at 190 °C and proceeding rapidly at 280 °C with complete decomposition to cerium oxide at 390-400 °C.

Application

Cerium (III) nitrate hexahydrate is widely used as a source of cerium, especially in the synthesis of micro- or nano-structured ceria (cerium oxide). Because of its high solubility and low decomposition temperature, cerium (III) nitrate hexahydrate is an ideal reagent for hydrothermal reactions, sol-gel processing, and co-precipitation and calcination reactions. Our cerium (III) nitrate hexahydrate 99.999% is designed for applications that demand high-purity cerium with low contaminants of other trace metals and rare earth metals. For example, high-purity cerium nitrate is applicable in studies using cerium (III) nitrate hexahydrate used to dope catalysts, such as recent efforts to boost water splitting using Ce-doped layered double hydroxides [1][2]. It is also applicable in studies using cerium (III)nitrate hexahydrate to build a ceria support for single-atom catalysts, such as nickel-doped ceria for the hydrogenation of acetylene[3] and platinum-doped ceria for carbon monoxide oxidation[4]. Our high-purity cerium (III) nitrate hexahydrate is also in the solid-state synthesis of cerium-doped phosphors like Ca₂YHf₂Al₃O₁₂ where energy transfer from Ce³⁺ to other rare earth ions plays a major role in the efficiency and breadth of excitations.[5]
