Descripción

Descripción general

Cerium(III) chloride heptahydrate is a hygroscopic crystalline solid. It is soluble in water and forms acidic solutions. It is used as a cerium source in various applications such as nanometal oxide synthesis and catalysis.

Aplicación

Cerium(III) chloride heptahydrate can be used:

• As a precursor to prepare cerium oxide nanoparticles for biomedical applications and photocatalytic degradation.
• As a solution to fabricate thin films of CeO₂ on glass substrates by the spray pyrolysis process.
• As a dopant to fabricate ZnO and CeO₂ nanocrystals for electrochemical sensing of H₂O₂ and photocatalytic degradation of Rhodamine B and Congo red dyes.
• As an additive to prepare corrosion-inhibiting formulations and coatings.
• To synthesize carbon nanofiber composites to fabricate high-temperature polymer electrolyte membrane fuel cell cathodes.
• As a support for the combination of cerium(III)chloride heptahydrate and sodium iodide supported on silica gel to promoteMichael-type additions. These catalysts are used to convert from indolesand nitroalkenes to 2-indolyl-1-nitroalkane derivatives in good yields.
