英文摘要	The Pd/active-carbon catalyst was prepared in solution through a reduction of Pd-II with formaldehyde, and the obtained metallic particles were around 10-30 Angstrom with a mean size about 16 Angstrom either applying ultrasound in catalyst preparation or varying palladium loading (0.8-5 wt.%). H-2 spillover from Pd onto the carbon surface could occur in Pd/C at 200 degrees C, and H/Pd decreased with the increase of Pd loading; the ultrasound in Pd/C preparation led to a greatly increased amount of spillover H-2, and H/Pd could reach a high value of 6.8 for 0.8 wt.% sonicated Pd/C catalysts. The Pd/C activity (mole H-2/min.g.Pd) in nitrobenzene hydrogenation at 30 degrees C increased with the palladium loading.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000071952700027&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Physical; SCI(E); CPCI-S(ISTP); 8
