| Outline of Annual Research Achievements |
In this study, the effects of various carbon nanostructures on the electrocatalytic and capacitance performances of carbon supported platinum (Pt/C) electrocatalysts were evaluated experimentally and numerically. The dense, hollow, and porous Pt/C catalysts were prepared using aerosol spray pyrolysis followed by microwave processes. Electrochemical surface area of porous Pt/C catalyst was more than twice than those of hollow or dense Pt/C. The results also showed the importance of a balance between mesopores and macropores. A fluid flow model showed that good oxygen transport contributed to the catalytic activity. Furthermore, N doping to porous carbon may further increase the electrocatalytic performance. While, the formation of hollow spherical carbon gave a good capacitance performance.
