abstract = {Carbon aerogels prepared at different carbonization temperatures and with
varying mesopore volumes were used as supports for Pt catalysts to study the n-C4H10/H2
reaction. Mean Pt particle size depended on the mesopore volume of the support, showing
a linear decrease when the mesopore volume increased. The turnover frequency (TOF) for
hydrogenolysis was much higher than for isomerization in catalysts supported on carbon
aerogels obtained at 900–950 °C. However, both TOF values were similar in catalysts
supported on the carbon aerogel obtained at 500 °C. TOF for hydrogenolysis and
isomerization were related to the mean Pt particle size in catalysts supported on carbon
aerogels obtained at 900–950 °C. In addition, both reactions showed a compensation effect
between the activation energy and pre-exponential factor, indicating that they have the
same intermediate, i.e., the chemisorbed dehydrogenated alkane.},
