Schematic of various Fe and Fe/Pd nanoparticle synthesis. (a) Silica-gel based synthesis of zero-valent iron nanoparticles for reductive dechlorination or iron/iron oxide nanoparticles for oxidative dechlorination. (b) “green” synthesis of bimetallic particles where excess reducing agent inhibits oxidation as well as agglomeration of particles. In this reaction, ascorbic acid is oxidized to dehydroascorbic acid.
