Na.ocluster forma.ion of a.meta.lic pla.inum (Pt) coa.ing, on ma.ga.ese oxide inorga.ic membra.es impregna.ed with multiwa.l ca.bon na.otubes (K-OMS-2/MWCNTs), a.plied by rea.tive spra. deposition technology (RSDT) is discussed. RSDT a.plies thin films of Pt na.oclusters on the substra.e;the thickness of the film ca. be ea.ily controlled. The K-OMS-2/MWCNTs fibers were enclosed by the thin film of Pt. X-ra. diffra.tion (XRD), sca.ning electron microscopy/X-ra. energy dispersive spectroscopy (SEM/XEDS), focus ion bea./sca.ning electron microscopy (FIB/SEM), tra.smission electron microscopy (TEM), a.d X-ra. 3D micro-tomogra.hy (MicroXCT) which ha.e been used to cha.a.terize the resulta.t Pt/K-OMS-2/MWCNTs membra.e. The non-destructive cha.a.teriza.ion technique (MicroXCT) resolves the Pt la.er on the upper la.er of the composite membra.e a.d a.so shows tha. the membra.e is composed of sheets superimposed into sta.ks. The na.ostructured coa.ing on the composite membra.e ma.eria. ha. been eva.ua.ed for ca.bon monoxide (CO) oxida.ion. The functiona.ized Pt/K-OMS-2/MWCNTs membra.es show excellent conversion (100%) of CO to CO2 a. a.lower tempera.ure 200℃ compa.ed to the uncoa.ed K-OMS-2/MWCNTs. Moreover, the Pt/K-OMS-2/MWCNTs membra.es show outsta.ding sta.ility, of more tha. 4 da.s, for CO oxida.ion a. 200℃.
