Application

  • Cerium acetate hydrate is a key precursor in spray pyrolysis for CeO₂ thin films, enabling selective and stable xylene sensing at room temperature for air quality monitoring.
  • It supports sonochemical synthesis of CeO₂ nanostructures with rich oxygen vacancies, boosting catalytic efficiency in CO oxidation.
  • It facilitates one-step synthesis of Pt-Ni@CeO₂ catalysts by providing Ce³⁺ and OH⁻, improving structural stability and catalytic performance in phenylacetylene hydrogenation.
  • It is used to hydrothermally synthesize Ce-doped WO₃ microrods on FTO glass, enhancing photocurrent for sensitive ascorbic acid detection in food safety sensors.

Features and Benefits

  • With a purity level of 99.9%, this product meets the stringent requirements ensuring reliable performance in various applications.
  • Low levels of trace contaminants ( < 1500.0 ppm) ensure minimal interference in sensitive applications, making it suitable for high-precision applications.

General description

Cerium(III) acetate hydrate, also known as cerium triacetate, is a high purity, water-soluble, and eco-friendly cerium precursor that decomposes to cerium oxide on heating. It is widely used for thin film fabrication, synthesis of cerium oxide (CeO₂) nanoparticles, and functional coatings in electronics, optics, and catalysis.
