Over the last few years, supported catalytically active liquid metal solutions (SCALMS) were shown to be remarkably efficient catalysts for alkane dehydrogenation. The active phase of these catalysts consists of a liquid metal matrix, in which catalytically active transition metals are dissolved. So far, only Gallium was used as a liquid matrix material, because of the low toxicity and low melting point. Since extensive research has already been made on Gallium-based SCALMS systems with different catalytically active transition metals, varying the matrix material is the logical next step to further improve the catalyst performance. These efforts are now extended to ternary systems such as GaInPt and GaSnPt. This extension opens up new questions as it increases the complexity, but also brings exciting new properties and insights into the dynamics of liquid SCALMS catalysts. In this talk, the most recent results regarding these ternary systems will be presented, with an emphasis on photoemission studies. Funded by SFB 1452.
