Galvanic oxidation of bimetallic Zn-Fe nanoparticles for oxygen scavenging

• Hybrid sputtering/ gas agglomeration system produces bimetallic Zn-Fe NPs as oxygen scavengers. The atomic arrangements of the allow to control oxidation mechanism. Galvanic couple between Zn –Fe accelerates process. Molecular dynamic simulations show effect galvanic for Bimetallic nanoparticles (NP) have demonstrated outstanding multifunctional characteristics, which depend on their size, distribution and composition. In this study, we possibility tailoring behavior produced by magnetron sputtering system. Fe metals were coupled promote faster Zn, stimulating a mechanism due dissimilar corrosion potential in nanoparticles. results revealed dissolution occurring at high humidity environments where no intermix exists Fe; however, such is excluded ZnFe alloys. was confirmed molecular simulations. This can be exploited moisture-activated scavenger materials acceleration
