Palladium nanoparticles supported on reduced graphene oxide (Pd/rGO) catalyst was prepared by using alovera extract in sunlight. The catalyst (Pd/rGO) was employed for the Suzuki cross coupling reactions. The characterization of Pd/rGO was done by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD). The average particle size of Pd was found to be 7±2 nm. The compound showed excellent catalytic activity with good recyclability for C-C cross coupling reactions.

The copper nanoparticles (Cu NPs) and amide functionalized graphene oxide (Cu-Amd-RGO) catalyst were prepared. This prepared catalyst (Cu-Amd-RGO) used for the synthesis of tetrazole derivatives. The catalyst (Cu-Amd-RGO) was characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction analysis (XRD). The average particle size of Cu was found to be 7.6 nm. The Cu-Amd-RGO catalyst exhibited excellent catalytic activity and recyclability for synthesis of tetrazoles.
