Özet

In this study, we reported the degradation of organic dyes (methyl orange, MO and methylene blue, MB) by Fe3O4@His@Ag MRC in which histidine was used as linker. The size of crystallite of MRC was calculated as 19 nm. The M-H hysteresis loop of the product indicates that it exhibits superparamagnetic property at room temperature. Catalytic studies showed that this product could catalyze the degradation of MO and MB in a reasonable time. Moreover, the product can be recycled five times by magnetic separation without major loss of its activity. Thus, Fe3O4@His@Ag MRC can be served as an effective and convenient recyclable nanocatalyst for azo dye degradation and hence as an environmental protection application too.
