The reactivity of Nanoscale Zerovalent Iron (nZVI) can be enhanced by addition of the second metal to increase surface area. In this research, the influence of pH and oxygen supply on Fe-Cu bimetallic nanoparticles' reactivity was investigated. Fe-Cu nanoparticles were synthesized through ferric chloride reduction by sodium borohydride followed by deposition of Cu metal. Iron dissolution was enhanced in acidic pH due to the presence of H+ ions which make the surface to be positively charged whereas in alkaline pH, the OH- ions contribute to the passive layer formation thus limiting further oxidation. Continuous supply led to higher Fe-Cu corrosion as opposed to limited oxygen supply since oxygen enhanced oxidation. The significance of this study is to make deductions in contaminant remediation technologies.
