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 (CeO) nanoparticles, and functional coatings in electronics, optics, and catalysis.

Application

  • Cerium acetate hydrate is a key precursor in spray pyrolysis for CeO thin films, enabling selective and stable xylene sensing at room temperature for air quality monitoring.
  • It supports sonochemical synthesis of CeO nanostructures with rich oxygen vacancies, boosting catalytic efficiency in CO oxidation.
  • It facilitates one-step synthesis of Pt-Ni@CeO 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.
