Fuel Cell-Related Reaction Activities of Nanoporous Metallic Platinum
The nanoporous structure and catalytic activities of a new nanoporous metallic platinum (NMP) were studied. The SEM image and N 2 adsorption isotherm of NMP indicated that NMP is highly microporous and mesoporous compared with Pt black (PB). The gas-phase reactivity of NMP for the water-formation re...

| description | The nanoporous structure and catalytic activities of a new nanoporous metallic platinum (NMP) were studied. The SEM image and N 2 adsorption isotherm of NMP indicated that NMP is highly microporous and mesoporous compared with Pt black (PB). The gas-phase reactivity of NMP for the water-formation reaction at 247 K showed that NMP has a catalytic activity that is 1.6-times higher than that of PB after 60 min and a reaction rate constant that is three-times larger than that of PB. On the other hand, NMP dispersed on a glassy carbon plate (GC) with Nafion® 117 showed an electrochemical reactivity towards methanol electro-oxidation that was lower than that of PB on the same GC electrode. However, the poisoning resistance of NMP on the GC electrode was higher than that of PB under the same conditions. |
