| Application: | Cobalt(II) chloride hexahydrate can be used as a catalyst: • To convert various aldoximes into corresponding nitriles in the presence of an inorganic base. • To prepare organic-inorganic polyvinylidene fluoride nanofiber composites (PVDF/CoCl2) for the production of pure hydrogen production from NaBH4. It can also be used as a cobalt precursor to synthesize nickel-cobalt-based binary metal phosphide (NiCoP) hollow spheres, which are used for electrocatalysis and energy storage (supercapacitor) applications. |
| General description: | Cobalt(II) chloride hexahydrate is a hydrated form of cobalt chloride. It is used as a catalyst for various organic reactions such as acetylation and tosylation of alcohols, chemoselective reduction of carboxylic esters, and condensation reactions. |
