Fe 3 O 4 /SBA‐16‐functionalized melamine–α–chloroacetic acid group‐supported Au nanoparticles are found to serve as heterogeneous and recyclable materials for the reduction of organic dyes such as Methylene Blue (MB) and Methyl Orange (MO) in aqueous solutions. A mesoporous structure with an average pore size of 3.39 nm and a surface area of 376 m 2 /g was characterized with the transmission electron microscopy (TEM), X‐ray diffraction (XRD) patterns, scanning electron microscopy (SEM), small angle x‐ray scattering (SAXS), and FT‐IR. Moreover, the specific surface area of the structure was determined using the Braunauer‐Emmett‐Teller (BET) method. The dye reduction activity of Fe 3 O 4 /SBA‐16‐MH−Au was investigated by reducing the MB and MO. The results demonstrated that the nonporous silica (NPS) was an effective system with high catalytic activities and had a prospective application for catalytic MB and MO.
