摘要：

We propose a 3D catalyst of polyaniline-coated glassy carbon microspheres decorated with nano-palladium (3D nanoPd@PANi/GCM) for methanol oxidation in direct methanol fuel cells (DMFCs). The 3D nanoPd@PANi/ GCM catalyst was synthesized by a green, low-cost method using two-step chemical deposition. The surface morphology and structure of the 3D catalyst were characterized by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDX), Fourier transform infrared spectrometry (FTIR), and X-ray diffractom-etry (XRD). Electrochemical properties were evaluated using cyclic voltammetry (CV), electrochemical impe-dance spectroscopy (EIS), and chronoamperometry (CA). The 3D nanoPd@PANi/GCM catalyst exhibited a larger effective surface area, higher specific activity and catalytic stability, and more durability than a commer-cial Pd/C catalyst for methanol oxidation. The novel catalyst showed great potential as a new electrode mate-rial for DMFCs.
