General description
Nickel(II) acetylacetonate (Ni(acac)₂) is a high-purity, air-stable organometallic complex widely used as a catalyst and precursor in advanced material synthesis. Its chelated structure provides excellent solubility in organic solvents and thermal stability, making it suitable for solution and vapor deposition processes. Ni(acac)₂ is used in the fabrication of energy materials, nanostructures, and functional coatings. Its versatility and reactivity enable applications in catalysis, electronic materials, and the synthesis of high-performance inorganic compounds.
Application
Nickel(II) acetylacetonate can be used as:
- A precursor in sol-gel and hydrothermal processes to synthesize nickel oxide (NiO) nanostructures and thin films, which are widely applied in catalysis, energy storage (supercapacitors, batteries), and gas sensors.
- A precursor for chemical vapor deposition (CVD) and atomic layer deposition (ALD) of nickel-containing films, enabling the fabrication of high-purity, uniform coatings for electronic and magnetic devices.
- A catalyst or catalyst precursor in organic transformations and electrocatalysis, such as hydrogen evolution, oxygen evolution, and CO₂ reduction reactions, due to its ability to generate highly active nickel species under reaction conditions.
- A precursor to synthesize Ni-based nanomaterials such as NiO/C nanocomposite and crystalline NiO nanoparticles via different synthetic methods like non-isothermal decomposition and solvothermal method.
- A precursor to prepare Ni catalysts such as Nickel(II) complexes, and hierarchical Ni/beta catalysts for various organictransformations.
- A catalyst to promote Michael additions.
