General description

Nickel acetate hydrate is an organic acid salt. Nickel citrate hydrate is a green crystalline solid that is soluble in water. This compound is commonly used in various applications such as electroplating, catalysts, and as a precursor in the synthesis of other nickel-containing compounds. In electroplating processes, nickel citrate hydrate acts as a source of nickel ions for depositing a layer of nickel onto surfaces.

Application

Nickel citrate hydrate can be used as a Nickel precursor

  • To synthesize these catalysts, the nickel precursor solution was impregnated onto the surface of the AlMCM-41 support. The impregnated support was then subjected to suitable drying and calcination processes to remove any solvent or excess precursor and activate the catalyst. The catalyst prepared with nickel citrate demonstrated stronger metal-support interaction, higher metal dispersion, and superior catalytic activity compared to those prepared with nickel nitrate and alkaline tetraamine nickel nitrate. The enhanced metal-acid interaction and (de)hydrogenating capability of this catalyst resulted in the highest catalytic activity and isomerization selectivity in n-dodecane hydroconversion.

  • In the synthesis of LaNiO3 perovskite, the Pechini method is employed due to its superior capabilities in achieving precise stoichiometric control, excellent reproducibility, and homogeneous product formation. This technique outperforms physical methods in ensuring the desired composition and quality of the LaNiO3 perovskite material.

Features and Benefits

  • Water soluble
  • Medium purity (99.9%)
  • Low trace metals in ppm level
  • Cost effective
  • Low Chloride and sulfate levels
