This book describes green chemistry approaches that employ liquid or supercritical carbon dioxide. Supercritical fluids have been investigated for more than a century however, applications to chemical synthesis and materials processing are relatively new. Since the 1990s, we have witnessed a veritable explosion of increased research activity in the area of chemical reactions and processes in liquid or supercritical carbon dioxide with the...

One of fee key areas within fee realm of green chemistry is fee identification of environmentally benign, alternative solvents ftiat can replace fee conventional, toxic, volatile organic solvents. Supercritical fluids (SCF) offer great... 

These alternative reactor technologies can be combined with Green Chemistry methods including, for example, catalytic membrane reactions and continuous flow supercritical fluid reactions. 

Polypyrrole nanocomposites with iron oxide and other nanoparticles have been prepared by several methods. For example, in situ chemical oxidative polymerization approach with either ultrasonication [59] or mechanical stirring [60] was reported. The nanocomposites showed particle-loading-dependent magnetic properties and electric conductivity. In addition, a supercritical fluid approach, implemented because of green chemistry, was also reported to be used as a medium in in situ chemical oxidative polymerization for the fabrication of conductive-polymer magnetic nanocomposites [61].
