By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Applied Catalysis Research have been presented. According to news reporting from Hangzhou, People's Republic of China, by NewsRx journalists, research stated, "Ni2O3-around-Pd hybrid can be fabricated on graphene oxide (Pd-Ni/RGO) by a simple one-pot wet chemical route. These isolated Pd clusters showed significantly improved performance for Suzuki coupling reaction compared to that of pure Pd/RGO, Ni2O3/RGO, popularly reported Pd/AC, as well as homogeneous PdCl2 and PdCl2(PPh3)(2)."

The news correspondents obtained a quote from the research from Zhejiang University, "Characterizations disclosed that Ni2O3 plays multiple roles in exfoliating graphene sheets, mediating the size as well as stability of Pd clusters. Pd-Ni/RGO dispersed homogeneously in the aqueous reaction mixture, exhibited high enrichment towards reactants as well as extremely high activity and stability for the Suzuki coupling reaction. The best turnover frequencies of all Pd atoms reached 38,750 h(-1) at 80 degrees C for bromobenzene coupling."

According to the news reporters, the research concluded: "It was concluded that the intimate interaction between Ni2O3 nanoparticles and Pd clusters appears to be beneficial for activating the Pd surface for the catalytic cycle."
