General description

Lanthanum(III) nitrate hydrate is a white crystalline solid that is highly soluble in water. It is also utilized in various fields such as catalysts, ceramics, and as a source of lanthanum ions in chemical synthesis.

Application

Lanthanum(III) nitrate hydrate can be used:
  • As a starting material to synthesize lanthanum zirconate nanoparticles.
  • As a precursor to prepare luminescent lanthanum-tricarboxytriphenylamine (La-TCA) coordination polymer nanosheets.
  • To fabricate perovskite oxide-type LaFeO3 dendrites for chemical sensors.
  • To synthesize LaMnO3 perovskite catalysts by using citric acid sol–gel method and La0.6Sr0.4MnO3 perovskites via coprecipitation method. The LaMnO3 perovskite catalysts has used for the oxidation of propane for emission control of hydrocarbon volatile organic compounds.
