Descrizione generale

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.

Applicazioni

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.

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.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
