Chapter 5 - Environmentally Benign Route for Nanomaterial Synthesis by Using SCW

Abstract

Nanomaterials are known for their unique mechanical, chemical, physical, thermal, electrical, optical, electronic, magnetic, and specific surface area properties. Supercritical fluid technology is also expected to contribute to new materials synthesis with green sustainable chemistry, especially tonanomaterials. In this chapter, we first introduce the principles of supercritical hydrothermal synthesis. Second, designing the reactor, especially for rapid mixing and precise temperature control, is explained. Then, we summarize some specific features of supercritical hydrothermal synthesis method. This method is extended to organice inorganic hybrid NP synthesis. This provides the fabrication of “superhybrid nanomaterials”.
