Description générale

Zinc sulfate heptahydrate is a white crystalline solid commonly used as an electrolyte additive in batteries, particularly in zinc-carbon batteries. Additionally, it can be used as a corrosion inhibitor in batteries and a precursor to synthesize nanoparticles.

Application

Zinc sulfate heptahydrate can be used:
  • As an electrolyte for rechargeable hybrid aqueous batteries.
  • As a precursor to synthesize ZnO nanoparticles.
  • As a cathodic corrosion inhibitor in batteries.
Zinc sulfate heptahydrate coated activated carbon can be used in water filtration.

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.
