Graphene-supported Palladium composites were prepared through irradiation of the mixture of K2C2O4, Pd and graphene oxide (GO) with UV light in the presence of ethylene glycol (EG). Since the two-dimensional sheet of GO has a huge surface area, the as-synthesized graphene supported Pd composites kept excellent catalytic activity. There is no reduction agents that were used in the process of synthesis of graphene supported Pd composites. The good yield of cinnamic acid could be obtained when using the as-synthesized graphene-supported Pd composites as a catalyst in the reaction of iodobenzene, acrylic acid and triethylamine in the water system. Furthermore, no obvious mass loss of catalyst could be observed when being used to catalyze the heck reaction multiple times.

Catalityc removal of nitrogen oxide from combustion gases Nitrogen oxide conversion to nitrogen over Pt/Al2 O3, Pd/Al2O3, Rh/Al2O3 catalysts was investigated. The results of the catalytic activity investigations, with the iso-x method, showed that NO reduction by methane occurs at a reasonable rate at the temperature range 200-500°C. Alumina-supported Pd, Pt and Rh catalysts have been compared for the selective reduction of NO to N2. All the catalysts showed good activity in NO reduction by methane, giving around 80 - 90% N2 production. At moderate temperatures Pt is the most active catalyst for the removal of NO.
