Abstract :Rhodiuminsert ignore into journalissuearticles values(III); ions were first impregnated on the surface of tungsteninsert ignore into journalissuearticles values(VI); oxide insert ignore into journalissuearticles values(WO3 ); in aqueous solution and reduced with aqueous NaBH4 to form rhodiuminsert ignore into journalissuearticles values(0); nanoparticles insert ignore into journalissuearticles values(Rh NPs); on the surface of WO3. After the isolation of the Rh NPs/WO3 catalyst by centrifugation, it was characterized by advanced analytical techniques. The results reveal the successful formation of Rh NPs on the surface of WO3. Rh NPs/WO3 catalyst with a turnover frequency value of 131 h-1 was found to be very active in hydrogenation of neat benzene at 25.0±0.1ºC.
