    abstract = {Liquid organic hydrogen carrier (LOHC) systems offer a particularly interesting option for chemical hydrogen storage.
In order to characterize and understand the endothermal hydrogen release from the carrier liquid and to evaluate suitable
catalyst materials, knowledge of the temperature fields in the dehydrogenation reactor is important. One suitable technique
for planar temperature sensing in reacting systems is phosphor thermometry. It is based on the excitation of a luminescent
material by a laser pulse and detection of the subsequent phosphorescence signal. We investigated the luminescence of the
thermographic phosphor (Sr,Ca)SiAIN3:Eu2+ (“SCASN:Eu2+”) dispersed in the H0-DBT / H18-DBT LOHC system in a
temperature range from 400 to 600 K. A measurement cell enables repeatable and homogeneous measurement conditions
of the hydrogen release reaction. A catalytic plate was put inside the heated LOHC. Temperature fields during the hydrogen
release reaction were measured for the first time using the phosphorescence decay time (PDT) and the phosphorescence
intensity ratio method (PIR). As expected, a strong cooling at the catalyst surface during the endothermal hydrogen release
reaction could be observed, which was quantified to be in the range of 40 K.},
