General description

Nickel(II) acetate tetrahydrate is a high purity coordination compound commonly employed in the synthesis of advanced materials, catalytic systems, and electrochemical devices. With a trace metals purity of 99.995%, it is particularly suited for applications requiring minimal contamination, such as nanostructure fabrication and thin-film deposition. The compound is supplied as crystalline solids or chunks and exhibits good solubility in water and polar organic solvents, facilitating its use in various solution based processes.

Application

Nickel(II) acetate tetrahydrate is used
  • To form a Ni(II) Schiff base complex on magnetic nanoparticles, which serves as a nanocatalyst for producing 3,4-dihydropyrimidine-2(1H)-ones through a solvent-free Biginelli reaction.
  • Precursor to prepare a nickel-containing solution for decorating CeO₂ nanostructures, resulting in NiO/CeO₂ nanocomposites
  • In the electrospinning synthesis of Ni-decorated carbon nanofibers (Ni-CNFs), for potential applications in magnetic devices, microwave absorbers, supercapacitors, and batteries.
Used in synthesis of polynuclear-nickel polyoxotungstate cluster compounds that are ideal for the design of molecular magnets.

Features and Benefits

  • Nickel(II) acetate tetrahydrate, 99.995% purity is vital for solar cell performance, as impurities can harm carrier recombination, charge transport, and overall device stability.
  • Analyzing 32 elements at ppm levels, particularly heavy metals like lead, cadmium, and arsenic, ensures optimal performance.
