Abstract
Background: The promising properties of Zinc Phosphate (ZnP) Nanoparticles (NPs) have made them come into prominence as one of the most favorable catalysts in various industries with ever- increasing applications. Among several proposed synthetic methods, biological methods have mostly been desired for their sheer person-environment compatibility in comparison with those of chemical and physical ones.
Objective: Therefore, the synthesis of ZnP NPs via biological route was developed in this study.
Method: Herein proposed a facile, applicable procedure for ZnP NPs via biosynthesis route, which included precipitation of Zinc Nitrate (Zn(NO3)2.6H2O) and diammonium hydrogen phosphate ((NH4)2HPO4) in the presence of Enterobacter aerogenes as the synthetic intermediate. Investigation of the anti-corrosion behavior of the synthesized NPs was explored on carbon steel in the hydrochloric acid corrosive environment to provide deeper insight into their unique anti-corrosion properties. Additionally, their antibacterial activities were also examined against Escherichia coli, Staphylococcus aureus and Streptococcus mutans.
Results: The results of X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, Field Emission Scanning Electron Microscope (FE-SEM) and the Energy Dispersive X-Ray Spectroscopy (EDS) analyses confirmed the successful synthesis of ZnP NPs. Moreover, the examinations of both anti-corrosion and antibacterial properties, revealed that the synthesized NPs could be a promising anti-corrosion/antibacterial agent.
Conclusion: ZnP NPs with an average size of 30-35 nm were successfully synthesized via the simple, suitable biological method. Results implied that these particles could be used as a non-toxic, environmentally friendly, corrosion-resistant and antibacterial agent instead of toxic and uneco-friendly ones.
Keywords: Bio-mediated synthesis, zinc phosphate nanoparticles, bacteria, Enterobacter aerogenes, anti-corrosion, antibacterial property.
