PUTHIYAPURA, V.K. ... et al., 2015. Development of a PtSn bimetallic catalyst for direct fuel cells using bio-butanol fuel. Chemical Communications, 51(69), pp. 13412-13415.
Pt and PtSn catalysts were studied for n-butanol electro-oxidation at various temperatures. PtSn showed a higher activity towards butanol electro-oxidation compared to Pt in acidic media. The onset potential for n-butanol oxidation on PtSn is ∼520 mV lower than that found on Pt, and significantly lower activation energy was found for PtSn compared with that for Pt.
