The elec.roc.talytic.ac.ivity for oxygen reduc.ion reac.ion （ORR） at neutral pH of c.trate-c.pped silver nanopartic.es （diam.ter = 18 nm. supported on glassy c.rbon （Gc. is investigated voltam.etric.lly. Novelly, the m.dific.tion of the substrate by nanopartic.es stic.ing to form.a random.nanopartic.e array and the voltam.etric.experim.nts are c.rried out sim.ltaneously by im.ersion of the Gc.elec.rode in an air-saturated 0.1 m.Nac.04 solution （pH = 5.8） c.ntaining c.em.c.lly-synthesized nanopartic.es. The experim.ntal voltam.ogram. of the resulting nanopartic.e array are sim.lated with hom.m.de program. ac.ording to the two-proton, two-elec.ron reduc.ion of oxygen to hydrogen peroxide where the first elec.ron transfer is rate determ.ning. In the c.se of silver elec.rodes, the hydrogen peroxide generated is partially further reduc.d to water via heterogeneous dec.m.osition. c.m.arison of the results obtained on a silver m.c.oelec.rode and silver nanopartic.es indic.tes that, for the silver nanopartic.es and partic.e c.verages （0.035%-0.457%） em.loyed in this study, the ORR elec.rode kinetic. is slower and the produc.ion of hydrogen peroxide larger on the glassy c.rbon-supported nanopartic.es than on bulk silver.
