The role of nickel traces in fine chemicals for hydrodechlorination reactions with zero-valent iron

Two different types of nanoscale zero-valent iron (nZVI) were synthesized according to the same standard procedure: reduction of dissolved Fe(II) with sodium borohydride – one starting from a commercial iron salt having pro analysi (p.a.) purity, and another from microscale iron with an extraordinary degree of purity, derived from the decomposition of iron pentacarbonyl. The ZVI samples exhibited similar hydrodechlorination activities towards...
