ZnS nanoparticle synthesis and stability of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) under glow discharge plasma

Ionic liquid glow discharge electrolysis for nanoparticle synthesis is an emerging nanomaterials processing technology and the stability of ionic liquid when they are in contact with plasma is an important issue. This paper discusses the stability of [BMIM][BF4] after exposing this ionic liquid to glow discharge plasma and the synthesis of cubic crystalline ZnS nanoparticles by plasma electrochemical method. Stability of the ionic liquid after plasma exposure to 20 min at 250 V is explained by their FTIR spectra and found that the ionic liquid is stable even after the plasma exposure.
