Lanthanum hydroxide (La(OH)3) is a rare novel earth compound which has so far been fabricated with various morphologies such as nanopowders, nanotubes, nanowires, nanorods and nanobelts from different methods like solvothermal, hydrothermal, sol-gel and template assisted routes. This compound has many attractive applications in gas-exhaust convectors, optical coatings, catalysts, superconductors, hydrogen storage materials and next generation of high dielectric constant gate dielectrics. It is a useful carrier precipitate for a number of ions. It was applied to the collection of traces of aluminum, bismuth, gold, iridium, iron, lead, thallium and titanium in silver metal. It is a predecessor Lanthanum oxide, which has a great interest as catalyst material.
