Pd supported on biguanide(metformine)-functionalized single-walled carbon nanotubes (SWCNT-Met/Pd2+) hybrid materials was fabricated for the first time. The prepared heterogeneous nanocatalyst was characterized by XRD, FT-IR, SEM, TGA and TEM. The catalytic activity of the prepared catalyst was investigated by employing Suzuki–Miyaura coupling reaction as a model reaction. A series of biphenyl compounds were synthesized through the Suzuki–Miyaura reaction using SWCNT-Met/Pd2+ as catalyst. The yields of the products were in the range from 80% to 95%. The catalyst can be readily recovered and reused at least 5 consecutive cycles without significant loss its catalytic activity.
