摘要: Abstract A facile preparation route for Pd electrocatalyst (Pd–Mn 3 O 4 /MWCNTs) composed of ∼3.5 nm Pd nanoparticles homogeneously anchored on Mn modified multi-walled carbon nanotubes (Mn is reported. The morphology, component and crystallinity the catalyst were characterized by means different techniques. electrochemical behavior Pd–Mn /MWCNT composites was examined cyclic voltammetry toward methanol electro-oxidation in alkaline media. binding surface /MWCNTs exhibited improved electrocatalytic activity anti-CO ads species poisoned ability compared to Pd/MWCNTs Pd/XC-72 (Pd/commercial Vulcan XC-72 black). This performance as-prepared attributed synergistic effect MWCNTs.
