This presentation will describe the synthesis of CdS/ZnS core/shell nanoparticles using the Successive Ionic Layer Adsorption and Reaction (SILAR) method with octadecene and oleic acid, and adaptation of this method to ionic liquids. We will discuss the effects of using different precursors (e.g., Cd, bulk CdS, Zn, CdO, Cd(OAc)2, ZnO, and Zn(OAc)2) for nanoparticle synthesis, and necessary procedural changes for nanoparticle synthesis going from octadecene and oleic acid to the ionic liquid 1-butyl-3-methylimidazolium methylsulfate [bmim][MeSO4]. We will then discuss our recent progress towards metal/semiconductor photocatalysts synthesized using ionic liquids. Methods to isolate particles from the ionic liquid and characterization of these materials by transmission electron microscopy, UV-visible spectroscopy, and fluorimetry will be presented.
