abstract = {Conventional fossil fuels such as gasoline or diesel should
be substituted in the future by environmentally-friendly
alternatives in order to reduce emissions in the transport
sector and thus mitigate global warming. In this regard,
iso-butanol is very promising as its chemical and physical
properties are very similar to those of gasoline. Therefore,
ongoing research deals with the development of
catalytically-supported synthesis routes to iso-butanol,
starting from renewably-generated methanol. This research
has already revealed that the dehydrogenation of ethanol
plays an important role in the reaction sequence from
methanol to iso-butanol. To improve the fundamental
understanding of the ethanol dehydrogenation step, the
Temporal Analysis of Products (TAP) methodology was applied
to illuminate that the catalysts used, Pt/C, Ir/C and Cu/C,
are very active in ethanol adsorption. H2 and acetaldehyde
are formed on the catalyst surfaces, with the latter quickly
decomposing into CO and CH4 under the given reaction
conditions. Based on the TAP results, this paper proposes a
reaction scheme for ethanol dehydrogenation and acetaldehyde
decomposition on the respective catalysts. The samples are
characterized by means of N2 sorption and Scanning
Transmission Electron Microscopy (STEM).},
