Highlights: • Mesoporous Cu–Pd ferrites were prepared by a facile, mild and environment-friendly route. • The catalysts have shown great efficiencies in Suzuki coupling reaction and up to 36.9 × 10{sup 3} h{sup −1} TOF can be obtained. • The catalyst can be magnetically separated easily and have shown prominent recyclability. - Abstract: Mesoporous Cu–Pd ferrites were prepared by using MCM-41 and SBA-15 mesoporous molecular sieves as hard templates and well characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), ICP-atomic emission spectroscopy, N{sub 2} adsorption–desorption and X-ray photoelectric spectroscopy (XPS). Compared with samples prepared by the sol–gel auto-combustion methods, the as-prepared mesoporous ferrites have shown uniform pore size and much higher specific surface areas. The samples showed a remarkably high activity in connection with the Suzuki coupling reaction, especially Cu{sub 0.99}Pd{sub 0.01}Fe{sub 2}O{sub 4} prepared by using MCM-41 as template obtained an excellent TOF as high as 36.9 × 10{sup 3} h{sup −1} and no obvious decrease in the activity was observed after ten consecutive runs.
