abstract = {The use of gallium‐rich, Supported Catalytically Active
Liquid Metal Solution (SCALMS) is a promising new concept to
achieve catalysis with atomically dispersed active metal
atoms. Expanding our previous work on short alkane
dehydrogenation, we present here the application of SCALMS
for the dehydrogenation of methylcyclohexane (MCH) to
toluene (TOL) using a Ga52Pt alloy (liquid under reaction
conditions) supported on silica. Cycloalkane dehydrogenation
catalysis has attracted great attention recently in the
context of hydrogen storage concepts using liquid organic
hydrogen carrier (LOHC) systems. The system under
investigation showed high activity and stable conversion of
MCH at 450 °C and atmospheric pressure for more than
75 h time‐on‐stream $(XMCH=15 \%)$ with stable
toluene selectivity (STOL) of $85 \%.$ Compared to
commercially available Pt/SiO2, the SCALMS system resulted
in higher yields and robustness. Baseline experiments with
Pt‐free Ga/SiO2 under identical conditions revealed the
decisive influence of Pt dissolved in the liquid Ga matrix.},
