Fe nanoparticles (zero-valent iron and iron oxide) have been regarded as an excellent type of environmental functional material with enormous surface area, outstanding reduction property and high reaction activity. However, in the common synthesis methods of Fe nanoparticles, the physical method usually requires extensive use of equipment for the reaction, and the reducing agent used in the chemical method is toxic, while the green synthesis method can effectively overcome the deficiencies of the conventional method. In this paper, methods were...
