This paper reports on the synthesis and use of CuPd nanoparticles supported on carbon, as highly active catalysts for the reduction of nitroarenes and Suzuki–Miyaura coupling reactions. The catalyst was characterized using the powder XRD, SEM, ICP-AES and EDS techniques. This method has the advantages of high yields, elimination of homogeneous catalysts, simple methodology and easy work up. Catalytic efficiency remains unaltered even after several repeated cycles.
