abstract = {As the search for carbon-efficient synthesis pathways for
green alternatives to fossil fuels continues, an expanding
class of catalysts have been developed for the upgrading of
lower alcohols. Understanding of the acid base
functionalities has greatly influenced the search for new
materials, but the influence of the metal used in catalysts
cannot be explained in a broader sense. We address this
herein and correlate our findings with the most fundamental
understanding of chemistry to date by applying it to d-band
theory as part of an experimental investigation. The
commercial catalysts of Pt, Rh, Ru, Cu, Pd, and Ir on carbon
as a support have been characterized by means of SEM,
EDX-mapping, STEM, XRD, N2-physisorption, and
H2-chemisorption. Their catalytic activity has been
established by means of c-methylation of ethanol with
methanol. For all catalysts, the TOF with respect to
i-butanol was examined. The Pt/C reached the highest TOF
with a selectivity towards i-butanol of $89\%.$ The trend
for the TOFs could be well correlated with the d-band
centers of the metal, which formed a volcano curve.
Therefore, this study is another step towards the
rationalization of catalyst design for the upgrading of
alcohols into carbon-neutral fuels or chemical feedstock.},
