一般說明

Cobalt(II) nitrate hexahydrate is an inorganic compound soluble in water. It is used as a precursor for the synthesis of cobalt-containing ceramic materials, such as cobalt ferrites and cobalt-doped titanium dioxide, which have magnetic, electrical, and photocatalytic properties. In addition, it finds use in electrochemical applications, such as in lithium-ion battery cathodes and fuel cell catalysts, due to the redox activity.

應用

Cobalt(II) nitrate hexahydrate can be:      
  • Used as a precursor to synthesize nano-Co3O4 via direct thermal decomposition method for electrochemical water oxidation applications      
  • Used as a precursor to synthesize single-crystalline Co3O4 powders with controllable morphology for lithium-ion battery applications.      cobalt-containing nanomaterials, such as nano-Co3O4, with controlled size, shape, and morphology via sol-gel method.      
  • As a vital precursor to generate nickel-rich cathode materials (NMC, NCA) for lithium-ion batteries using co-precipitation process because of its simplicity, ease of scale-up, and ability to produce a homogeneous structure at the particle scale.

Cobalt(II) nitrate hexahydrate can be used as a:      
  • A starting material in the preparation of Co-based nanomaterials and Co complexes.      
  • A catalyst to synthesize 5-carboxanilide-dihydropyrimidinone derivatives via a three-component condensation reaction.     
  • A dopant to prepare LaCr1−xCoxO3 solid-solution ceramics for high temperature applications.

特點和優勢

  • High purity with trace metal analysis (=< 15 ppm) for 32 elements, suitable for batteries.     
  • High water solubility ideal for synthesizing composites for various applications.
  • Low ppm levels of metal ions including Al, K, Na, Mg, Cu, Co, etc.
