Solvent-Free Synthesis Of Metal Coordination Compounds Using Ball Mills, Jenna Cantway
Solvent-Free Synthesis Of Metal Coordination Compounds Using Ball Mills, Jenna Cantway
Masters Theses & Specialist Projects
Mechanochemistry utilizes mechanical energy to promote chemical reactions to completion. Samples ground with a ball mill are placed under consistent pressure and temperature, which allows for increased surface area, shorter reaction times and overall better control of reaction conditions compared to the use of a mortar and pestle. Many synthetic techniques to prepare metal coordination compounds use a solvent. The solvent promotes the reactions by providing a route for reagents to interact. While solvents facilitate reactions, there is interest in reducing or eliminating solvents altogether during the synthesis process due to potential instability of a solvent under certain experimental conditions …

Synthesis Of Cds/Zns Core/Shell Semiconductor Nanoparticles, Austin Skyler Antle
Masters Theses & Specialist Projects
Core/shell semiconductor nanoparticles are of great interest as photocatalysts due to their large surface area per volume and tunable band gaps. The synthesis of core/shell semiconductor nanoparticles has traditionally involved the use of binding ligands to ensure the particles do not aggregate. These binding ligands lower the surface area of the nanoparticles though, reducing their overall efficiency. Ionic liquids have been found to be capable of acting as both solvents and stabilizing agents for synthesis of catalysts with highly active surfaces. Our experiments focus on the synthesis of CdS/ZnS core/shell nanoparticles with the ionic liquid 1-butyl-3-methylimidazolium methyl sulfate, [BMIM][MeSO4], acting …
