Microwave-Assisted Synthesis of Single-Crystalline Tellurium Nanorods and Nanowires in Ionic Liquids

摘要

Many chemical processes involve volatile organic solvents that evaporate into the atmosphere with detrimental effects on the environment and human health. As the introduction of cleaner technologies has become a major concern throughout both industry and academia, the search for alternatives to the damaging volatile solvents has become a high priority. Room-temperature ionic liquids (RTILs) have aroused increasing interest worldwide due to their high fluidity, low melting temperature and extended temperature range in the liquid state, air and water stability, low toxicity, nonflammability, high ionic conductivity, ability to dissolve a variety of materials, and importantly no measurable vapor pressure. Therefore, negative environmental and safety problems arising from the use of volatile organic solvents can be avoided by using RTILs. Because of the above reasons, RTILs are actively being explored as possible green solvents to substitute conventional volatile organic solvents in a variety of processes, including industrially important chemical processes. They also offer fascinating possibilities for fundamental studies of their effects on chemical reactions and synthetic processes.
