Description

General description

Lanthanum(III)acetate hydrate is a hydrated salt of lanthanum. It appears as a white oroff-white crystalline solid. It serves as a precursor for synthesizing variouslanthanum-based materials and plays an important role in the advancement ofnanomaterials, photovoltaics, photocatalysis, and semiconductor technologies.

Application

Lanthanum (III) acetate hydrate can beused as:

• An additive to improve the corrosion resistance of carbon steel via sol gelprocess. its presence helps in forming a protective layer that mitigates corrosion processes, particularly in harsh environments. It is an alternativefor Cr (VI) due to its excellent self-healing properties.
• A precursor in the synthesis of photoluminescentLaCO₃OH superstructures via solvent/catalyst-free one-step synthesis. LaCO₃OHsuperstructures further find application in light-emitting devices.
• A precursor in the sol-gel synthesis of magnesium and lanthanum-doped titaniumdioxide (Mg-La/TiO_₂) photoelectrodes, which significantly enhances thephotocatalytic performance of TiO₂ for use in dye-sensitized solar cells(DSSCs).

Used in the synthesis of a novel phenolate-bridged dilanthanum(III) complex which has potential as a model for metalloproteins as well as in basic and applied chemistry.
