摘 要：Nanostructured materials have attracted great attention in recent time because of their innovative characteristics and potential applications in the fields of catalysis, drug delivery, sensors and pollution abatement measures. Stabilized metal nanoparticles (size ＜ 10 nm) with very active surface atoms, high selectivity and recyclability have lead to a new generation of 'Nanocatalysts' for sustainable green chemistry for industrial applications like fine and bulk chemicals, Pharmaceuticals, fuel cell, petroleum refineries, environmental catalysis and many other fields. The present chapter summarizes the techniques for preparations, characterizations, and catalytic activities of different metals nanoparticles for organic transformations.
