Abstract: Abstract: Zero-valent iron nanoparticles were synthesized by hydrogenating [Fe[N(Si(CH3)3)2]2] at room temperature and a pressure of 3atm. To monitor the reaction, a stainless steel pressure reactor lined with PTFE and mechanically stirred was designed. This design allowed the extraction of samples at different times, minimizing the perturbation in the system. In this way, the shape and the diameter of the nanoparticles produced during the reaction were also monitored. The results showed the production of zero-valent iron nanoparticles that were approximately 5nm in diameter arranged in agglomerates. The agglomerates grew to 900nm when the reaction time increased up to 12h; however, the diameter of the individual nanoparticles remained almost the same. During the reaction, some byproducts constituted by amino species acted as surfactants; therefore, no other surfactants were necessary. [Copyright &y& Elsevier]
