General description

Electrodeposition of zinc on glassy carbon and nickel substrates in zinc chloride-1-ethyl-3-methylimidazolium chloride molten salt is studied.

Application

Zinc Chloride may be used:
  • as catalyst in knoevenagel condensation of carbonyl substrates with acidic methylene reagents
  • in the preparation of porous carbon nanofibers, useful in the fabrication of efficient electrodes for supercapacitors
  • as a catalyst in preparation of poly(propylene fumarate)
  • in the low temperature synthesis of nanocrystalline zinc oxide films
  • in the synthesis of zinc oxide nanoparticles with low agglomeration. Aqueous suspensions of the nanoparticles displayed high transmittance in the visible light range, but exhibited strong absorption in the UV range.
