Green chemistry becomes an eye-catching topic of interest in the past few years because it is a comfortable, secure, inexpensive, and eco-friendly way of synthesis. Iron oxide nanoparticles with different morphologies and sizes have been extensively studied due to their broad applications. Iron nanoparticles (Fe NPs) have drawn interest in site remediation and also in the treatment of organic or inorganic pollutants of water. The present review shows different synthesis methods of zero-valent and iron oxide nanoparticles from different plant extracts including tea extracts (Oolong tea, tea powder, tea waste, and tea polyphenols), from other plant extracts (Amaranthus dubius, Murraya koenigii, Eucalyptus, Syzygium aromaticum, curcuma, Ocimum sanctum, Emblica officinalis, Tridax procumbens, Dodonaea viscosa, Spinacia oleracea, Lawsonia inermis (henna), Gardenia jasminoides, Punica granatum, and Colocasia esculenta), from bio-microorganisms (Acinetobacter spp. bacterium, Aspergillus oryzae, Sargassum muticum), and from magnetite sand. The different potential applications of iron nanoparticles in remediation, in dye removal, and as an antibacterial agent point to the importance of iron nanoparticles in the environmental removal of contamination.
