Applications

Under microwave conditions, this ionic liquid can be used as a solvent for ZnO nanoparticle synthesis. It also offers improved CO ₂ solubility and can be used as a reaction solvent with higher concentrations of CO ₂ .

For the renewable energy industry, it can be used for:

• customized electrolytes in lithium/sodium ion batteries
• electrolytes that allow higher power densities in supercapacitors
• An organic solvent-free electrolyte for dye sensitized solar cells
