Abstract: Pt-Au/MWCNTs (multi-wall carbon nanotubes) electrocatalyst was prepared by microwave method, and characterized by SEM, TEM, and EDS techniques. The results showed that the Pt-Au nanoparticles were small and well dispersed on the surface of MWCNTs. The electrochemical behaviors were studied by rotating disk electrode (RDE) technique in 0.1 mol•L−1 HClO4 solution. The linear sweeping voltammetry (LSV) results indicated that Pt-Au/MWCNTs with mPt:mAu of 1:2 exhibited the highest catalytic activity for oxygen reduction.

Key words: Pt-Au/MWCNTs, Microwave synthesis, Oxygen reduction reaction (ORR)
