To inform EPA.
Description:
In continuation of our developmental program for sustainable pathways to nanomaterials, an account of greener preparation of nanoparticles utilizing naturally occurring reagents such as vitamins, sugars, tea extracts, and biodegradable polymers will be presented which reduces or eliminates the use and generation of hazardous substances. Using completely benign conditions and an innocuous source for reduction and capping the ensuing nanomaterials, we describe several greener alternatives for the production of nanoparticles utilizing vitamins, poly(ethylene) glycol (PEG), glutathione, and polyphenols from tea, wine and winery waste, red grape pomace. The use of microwave heating in some cases has reduced the processing time to merely few minutes. The application of ensuing particles in catalysis and environment will be highlighted.
