摘要:
Core-shell Fe@Fe2O3 nanowire is one special nanoscale zero-valent iron (NZVI) with an iron core and an outside shell of iron oxide containing the surface bound ferrous ions, which has been used to remove various pollutants including Cr(VI). However, it can be easily oxidized to accumulate iron oxides on the shell, resulting in the loss of reactive activity during its long-term application. Therefore, the dissolution of iron oxides by reduction is required to maintain NZVI reactivity. In this study, we combine NZVI and a dissimilatory iron reduc...
