Descrizione generale

Lanthanum(III) nitrate hexahydrate is a transition metal catalyst widely used in many organic transformations such as chemoselective deprotection of acetonides, acetylation of alcohols, phenols, and amines with acetic anhydride, and synthesis of α-amino nitriles. It can also be used as a precursor in the preparation of lanthanum-based nanoparticles.

Applicazioni

Lanthanum(III) nitrate hexahydrate can be used as a catalyst in the synthesis of:
  • α-aminonitriles by a one-pot three-component coupling of the carbonyl compound, amine, and TMSCN.
  • Acetals and geminal diacetates (acylals)from aldehydes.
  • Bis(indolyl) methanes under solvent‐free conditions.
It can also be used as a starting material for the electrochemical synthesis of LaMnO3 thin films and solvothermal synthesis of doped lanthanide oxysulfide (La2O2S).

Caratteristiche e vantaggi

  • Thermal stability
  • Low toxicity
  • Mild reaction condition
  • Chemoselectivity
  • Low cost

Lanthanide Ions as Photon Managers for Solar Cells

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).

Thermoelectric Performance of Perovskite-type Oxide Materials

The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.

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.
