“…Several iron nanoparticles such as biosynthesized zerovalent iron (Soliemanzadeh and Fekri, 2017a), magnetic iron oxide nanoparticles, bimetallic nanoparticles (Luo et al, 2016), trimetallic nanoparticles (Basavegowda et al, 2017;Mishra et al, 2015) and copper ferrite nanoparticles (Kombaiah et al, 2018a) have been reported. Carbon-, starch-, biopolymer-, and clay mineral -supported nanocomposites (Abujaber et al, 2018;Ghaedi & Arabi, 2018;Krishna et al, 2016;Ostovan et al, 2018;Soliemanzadeh and Fekri, 2017b;Wang et al, 2015) as well as magnetic core-shell silica and amino functionalized nanoparticles (Mahmoud et al, 2016b;Farzad and Veisi, 2017) have been designed to mitigate particle agglomeration and enhance dispersion.…”

The ever-increasing importance of green-based iron nanoparticles within the last decade and their environmental applications is a compelling reason to probe novel routes for their synthesis. Therefore, the principles of green chemistry, waste prevention, energy efficiency, safer solvents, and the benign precursor materials have become fundamental considerations in the synthesis process of these materials, birthing extensive study in this field. In this light, a comprehensive discussion of the successes of greener techniques and other biological nanotechnologies including the use of microorganisms (fungi, bacteria, actinomycetes, and viruses), algae, plant and their extracts for the synthesis of iron (Fe) nanoparticles (NPs) is presented. Although promising findings have been reported, substantial research gaps and the opportunity to capitalize on the emergence and rise of these eco-friendly sources have been identified. The application of synthesized nanoparticles for environmental remediation and their toxicological implications are also discussed.

“…In addition, Marková et al illustrated that doping a noble metal such as silver (Ag) on the surface of nZVI improved the reactivity of nZVI and the bimetallic (Fe-Ag) nanoparticles attained a 100% removal efficiency of 10 mg L -1 of phosphate (PO4 -3 ) [36]. Table 2 also demonstrates that several nZVI-based materials for instance, polyacrylamide coated nanoscale zero-valent iron particles (PPA-nZVI) [14], activated carbon supported nanoscale zero-valent iron particles (AC-nZVI) [37], magnesium hydroxide coated-nanoscale zerovalent iron nanoparticles (Fe 0 [Mg/Fe] 1.0 ) [38], encapsulated nanoscale zero-valent iron [39] , nanoscale zero-valent iron/nickel supported on zeolite (Z-Fe/Ni) [40], sepiolitenano zero valent iron composite [41], clay-supported nanoscale zero-valent iron [42], nanoscale zerovalent iron particles supported on spondias purpurea seed waste (S-NaOH-NZVI) [43], and nanoscale zerovalent iron particles (nZVI) derived from reducing natural goethite [44], were reported in the literature to efficiently remove high and low concentrations of phosphorus from water.…”

Several toxic substances, such as nutrients, heavy metals, radionuclides, and pharmaceuticals, are continuously discharging to the environment, as a result of unaccountable industrial and agricultural activities, and contaminating huge quantities of soil and water. Nanotechnology was employed over the past years to remediate the contaminated waters and clean the environment from these pollutants to protect the life on the planet. Nanoscale zerovalent iron (nZVI) is one of the most applied nanomaterials in the field of water and wastewater treatment and it is extensively utilized to remove a wide range of contaminants from water. Thus, this mini review intends to summarize the latest applications of nZVI and its composites in eliminating several nutrients and heavy metals, namely nitrate (NO3 -), phosphorous (P), chromium (Cr) and arsenic (As).

“…They showed that the resultant functional Fe/ bentonite nanostructure exhibited enhanced adsorption capacity, which can be used as the potential candidate for an environmental remediation especially for the removal of toxic Cr metals. They have also performed the effective removal of phosphorous from aqueous solution employing Fe/bentonite functional nanostructure . They found that the sorption capacity of the natural bentonite is about 4.61 mg⋅g −1 while that of functional Fe/ bentonite is found to be 27.63 mg⋅g −1 .…”

The bioreduction process, that utilizes the plant extracts, have been explored extensively as a green chemical route for the synthesis of metal nanoparticles due to their eco-friendly protocol as well as versatility in the selection of various plant resources. Recent advances in this plant extract mediated biological process are the fabrication of functional nanostructures. Bioreduction mechanism catalyzes the combining process of metal nanoparticles with other kind of materials including metal, metal oxides, cellulosic, zeolite and carbon nanomaterials. Integrating metal nanoparticles with various materials offers new functional properties and improves their performance comparing to their pristine counterpart. In this review, plant-based biochemical substances, which influence the metal ion into metal and their controlled nucleation on the surface of other kinds of materials are highlighted, and the future prospect of this bio-based synthesis of functional nanostructures are discussed.[a] M.
