摘要

Monoalkyl viologens are N-alkyl-4,4'-bipyridine salts that are being considered as catalysts for oxidation of carbohydrates in alkaline media. Cyclic voltammograms of these viologens have been run and the results are reported here. Simple-fuel-cell tests were also run, with homogeneous viologens as catalysts and primarily fructose as fuel, and it was found that, under otherwise identical conditions, the monoalkyl viologens produced a current about 40% of the current produced by the analogous dialkyl viologen. We conclude that bypiridine, immobilized so that it is functionally similar to monoalkyl viologen, should be tested as a heterogeneous catalyst in direct-carbohydrate fuel cells.
