Catalytic Application of Au NPs-rGO Composites

Zhang et al. showed that Au NPs-rGO composites have been efficiently used as catalysts for the Suzuki-Miyaura coupling reaction of chlorobenzene and phenylboronic acid [13], 

They suggested that the size and shape of the Au NPs are crucial to enhance the catalytic activity of the Suzuki-Miyaura coupling reaction of phenyl boronic acid and chlorobenzene. According to their report, flower-shaped Au NPs possess higher catalytic activity than the spherical Au NPs due to its smaller size of about 4 run and uniform distribution of particles. Also the yield of the desired product increases with increase in the concentration of the catalyst which clearly proves that Au NPs decorated on GO has excellent catalytic activity towards Suzuki-Miyaura coupling reaction of phenyl boronic acid and chlorobenzene.
