Review on nano zerovalent iron (nZVI): From synthesis to environmental applications
TL;DR: In this paper, the authors present the opportunities and risks arising from the use of nano zerovalent iron (nZVI) from its synthesis to environmental application, and identify problems that may occur a result of changes in the physicochemical properties of nZVI due to their modification (e.g. other metal doping, coating the surface, or deposition on the support).
