a. ha. been loa.ed （1% wt.） on different c.mmerc.a. oxide supports （c.O, La.O3, Y2O3, NiO） by three different methods： double impregna.ion （DIM）, liquid-pha.e reduc.ive deposition （LPRD）, a.d ultra.onic.0}ion （US）. Sa.ples were c.a.a.terised by N2 a.sorption a. -196℃, high-resolution tra.smission elec.ron mic.osc.py, selec.ed a.ea.elec.ron diffra.tion, energy dispersive X-ra. spec.rometry, high-a.gle a.nula. da.k-field ima.ing （Z-c.ntra.t）, X-ra. diffra.tion, a.d tempera.ure progra.med reduc.ion. c. oxida.ion wa. used a. a.test rea.tion to c.mpa.e the c.0}a.ytic.a.tivities. The best results were obta.ned with a. loa.ed by DIM on the NiO support, with a. a.tivity of 7.2 × 10^（-4） molc.·ga.^（-1）·s^（-1） a. room tempera.ure. This is most likely rela.ed to the a. na.opa.tic.e size being the sma.lest in this c.0}a.yst （a.era.e 4.8 nm）, sinc. it is well known tha. gold pa.tic.e size determines the c.0}a.ytic.a.tivity. Other sa.ples, ha.ing la.ger a. pa.tic.e sizes （in the 2-12 nm ra.ge, with a.era.e sizes ra.ging from 4.8 to 6.8 nm）, showed lower a.tivities. Nevertheless, a.l sa.ples prepa.ed by DIM ha. a.tivities （from 1.1 × 10^（-4） to 7.2 × 10^（-4） molc.·ga.^（-1）·S^（-1）, a. room tempera.ure） a.ove those reported in the litera.ure for gold on simila. oxide supports. Therefore, this method gives better results tha. the most usua. methods of deposition-prec.pita.ion or c.-prec.pita.ion.
