TUNGSTEN OXIDE MODIFIED ORDERED MESOPOROUS CARBON CATALYST FOR FORMIC ACID OXIDATION IN DIRECT FORMIC ACID FUEL CELLS |
| 摘要 |
Electrocatalysts for the anode electro-oxidation of formic acid in direct formic acid fuel cells (DFAFCs). The Pd-, Pt- or PdPt-based electrocatalysts contain WO3-modified ordered mesoporous carbon (OMC) as support material. Compositions and ratios of Pd:Pt in the electrocatalysts as well as methods of preparing and characterizing the catalysts and the WO3-OMC support material. |
