Effect of Micropore Distribution on Pt-Ru Dispersion onto Styrene-acrylonitrile (SAN)-based Porous Carbons for PEMFCs |
| 초록 |
In this work, we prepared styrene-acrylonitrile (SAN)-based porous carbons for using catalyst supports in polymer electrolyte membrane fuel cells (PEMFCs). Activated porous carbons were prepared by chemical activation methods with different temperatures. And Pt-Ru catalysts were deposited on prepared porous carbon. The structural features and the textural properties of activated SAN-based carbon supports were investigated by X-ray diffraction spectroscopy (XRD) and N2/77 K adsorption isotherms using Brunauer-Emmett-Teller (BET) equation, respectively. The surface morphology of carbon supports and catalysts were characterized by scanning electron microscope (SEM) and transmission electron microscopy (TEM). The electrochemical behaviors were measured by cyclic voltammetry (CV) in 0.5 M H2SO4 electrolyte. |
