1. A 50% increase in formic acid electrooxidation.
2. A shift in CO oxidation potential to lower values by ~50 mV.
The results presented here not only demonstrates the feasibility of using multi-walled nanotubes as supports for formic acid oxidation catalyst, but also shows a more energy efficient way to oxidize formic acid. These results can be the basis for evaluating other catalysts over nanotubes for formic acid oxidation. These results also assume a broader significance because of the rapidly growing commercial interest on formic acid as a benign portable energy source for different applications such as communication devices (cell phones) and data processors (laptops).
