A single-step green approach to the synthesis of nanoscale zero valent iron (nZVI) and nanoscale bimetallic (Fe0/Pd) particles using tea (Camellia sinensis) polyphenols is described.

The expedient reaction between polyphenols and ferric chloride (FeCl3) occurs within a minute at room temperature and is indicated by a color change from pale yellow to dark green/black as the iron nanoparticles are formed.

Tea polyphenols form complexes with metal ions in solution and reduce them to nanoscale iron. The synthesis of bimetallic catalysts,...
