ChinaAbstract In order to develop a novel and high-performance catalytic material for direct methanol fuel cells(DMFC),molybdenum oxide as a co-catalyst with Pt on multi-walled carbon nanotubes which were modified by titanium dio-xide(denoted as CNTs@TiO2) was investigated. The physicochemical characterizations of the catalysts were carriedout via X-ray diffraction(XRD), transmission ectron microscopy(TEM) and X ray pholoelectron spectroscopy(XPS).Cyclic voltammetry(CV) showed that the CO-tolerance performance increased in the sequence of PU/CNTs
