Outline of Final Research Achievements |
In this study, the effects of various carbon nanostructures on the catalytic performances of carbon supported platinum (Pt/C) electrocatalysts were evaluated experimentally and numerically. The Pt/C catalysts were prepared using a hybrid method involving the preparation of dense, hollow, and porous carbon particle via aerosol spray pyrolysis followed by microwave-assisted Pt deposition. Electrochemical surface area of porous Pt/C catalyst was more than twice than those of hollow or dense Pt/C. The effects of pore size on electrocatalysis were also studied. The results showed the importance of a balance between mesopores and macropores for effective catalysis with a high charge transfer rate. A fluid flow model showed that good oxygen transport contributed to the catalytic activity. Furthermore, the addition of N doping to porous carbon may further increase the electrocatalytic performance. While, the formation of hollow spherical carbon gave a good capacitance performance.
