The s.udy focus.d on the modification with platinum of dark defectiv. titania obtained v.a puls.d las.r ablation. Both the method of Pt introduction and the nature of the Pt precurs.r were v.ried. All s.mples.exhibited s.milar phas. compos.tions. s.ecific s.rface areas. and Pt contents. High-res.lution trans.is.ion electron micros.opy coupled with puls.d CO ads.rption rev.aled increas.d dis.ers.ty when photoreduction and the hydroxonitrate complex (Me _(4) N) _(2) [Pt _(2) (OH) _(2) (NO _(3) ) _(8) ] were us.d. The s.mple featured a high content of s.ngle-atom s.ecies.and s.bnano-s.zed Pt clus.ers. The X-ray photoelectron s.ectros.opy res.lts.s.owed that the photoreduction method facilitated the appearance of a larger number of Pt ^(2+) s.ates. which appeared owing to the s.rong metal-s.pport interaction (s.s.) eff ect of the trans.er of electron dens.ty from the electron-s.turated defects.on the TiO _(2) s.rface to Pt ^(4+) .
