Surface modification is widely assumed as a mandatory prerequisite for the real applicability of iron oxide nanoparticles. This is aimed to endow prolonged stability, electrolyte and pH tolerance as well as a desired specific surface chemistry for further functionalization to these materials. Nevertheless, coating processes have negative consequences on the sustainability of nanomaterial production contributing to high costs, heavy environmental impact and difficult scalability. In this view, bare iron oxide nanoparticles (BIONs) are arousing an increasing interest and the properties and advantages of pristine surface chemistry of iron oxide are becoming popular among the scientific community. In the authors’ knowledge, rare efforts were dedicated to the use of BIONs in biomedicine, biotechnology, food industry and environmental remediation. Furthermore, literature lacks examples highlighting the potential of BIONs as platforms for the creation of more complex nanostructured architectures, and emerging properties achievable by the direct manipulation of pristine iron oxide surfaces have been little studied. Based on authors’ background on BIONs, the present review is aimed at providing hints on the future expansion of these nanomaterials emphasizing the opportunities achievable by tuning their pristine surfaces.

Synthesis Of Nanoparticles

In recent years, nanotechnology has emerged as a start-of-the-art, with multifarious applications in a wide array of fields. Studies on green synthesis of nanoparticles moves forward these days. The present work involves the green method of synthesizing Iron oxide nanoparticles [Fe2O3] by Phyllanthus Niruri leaf extract and NaOH which acts as a precipitating agent. Furthermore, the green synthesized Iron oxide nanoparticles were characterized and its antibacterial activity was investigated. As this plant extract is more beneficial, it is energy efficient, low cost and environmentally friendly process than the biohazardous chemical synthesis. Iron oxide nano particles are gaining importance for their uses in environmental remediation technologies. The characterization of nano particles includes the IR, UV-Vis, and Size determination using SEM and XRD. The average crystalline size of the iron oxide nanoparticles was calculated by Debye’s Scherrer formula,d = 12.34nm. The analytical studies revealed that the synthesized Iron oxide nanoparticles almost have the identical size and morphology. Thus, the above studies concluded, the synthesized material was Iron oxide nanoparticles.

Background: : Iron Oxide nanoparticles have enormous applications in environmental remediation and catalysis. The synthesis of such nanoparticles through a green approach provides a significant advantage due to the non-toxic nature of the ingredients involved. Method: : In the present work, Diospyros lotus fruit extract was used for the synthesis of iron oxide nanoparticles (NPs). The plant biomolecules were extracted employing two different solvents, i.e. water and methanol. The effect of both the extracts on the reduction of metal salt as well as on the shape and size of the produced NPs was investigated. Results:: UV-Visible spectroscopy confirmed the synthesis of iron oxide NPs, Fourier Transform Infrared (FTIR) spectrum depicted the presence of biomolecules on the surface of NPs as capping agents, X-ray Diffraction (XRD) diffractogram confirmed the crystalline structure of mixed iron oxide NPs and Scanning Electron Microscopy (SEM) images showed the spherical shape of NPs. The synthesized NPs were exploited to catalyze the degradation of methylene blue dye in the Fenton type catalytic reaction. The degradation reaction was monitored using UV-Visible spectroscopy, which indicated that the percent degradation increased from 15% (without iron oxide NPs) to 91% in the presence of organic extract prepared iron oxide NPs and to 81% in the presence of aqueous extract prepared iron oxide NPs. The effect of the concentration of methylene blue and iron oxide NPs on the degradation process was also investigated. Conclusion: : The results indicated the potential of synthesized nanoparticles to promote catalytic reactions involved in environmental remediation.
