Merck, 228931-25G, Cerium(III) chloride heptahydrate

General description
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.
Application
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.
