Abstract:
Well-dispersed Ag nanoparticles (NPs) are successfully decorated on Fe 3 O 4 @SiO 2 nanorods (NRs) via a facile step-by-step strategy. This method involves coating α -Fe 2 O 3 NRs with uniform silica layer, reduction in 10% H 2 /Ar atmosphere at 450°C to obtain Fe 3 O 4 @SiO 2 NRs, and then depositing Ag NPs on the surface of Fe 3 O 4 @SiO 2 NRs through a sonochemical step. It was found that the as-prepared Ag-decorated magnetic Fe 3 O 4 @SiO 2 NRs (Ag-MNRs) exhibited a higher catalytic efficiency than bare Ag NPs in the degradation of organic dye and could be easily recovered by convenient magnetic separation, which show great application potential for environmental protection applications.
