Single Atom Sites in Ga‐Ni Supported Catalytically Active Liquid Metal Solutions (SCALMS) for Selective Ethylene Oligomerization Open
Supported catalytically active liquid metal solutions (SCALMS) are materials composed of a liquid metal alloy deposited on a porous support. Due to the dynamic properties of the liquid metal alloy, these systems are suggested to form singl…
Local Charge Distribution in GaxPdy Intermetallics: Characterizing Catalyst Surfaces from Large-Scale Molecular Mechanics Simulations Open
We combine the charge equilibration (QEq) method with the modified embedded atom model (MEAM) to describe a series of intermetallic GaxPdy compounds at near DFT accuracy. Apart from structure, energetics and elastic properties, a particula…
Unraveling the Effect of Rh Isolation on Shallow d States of Gallium–Rhodium Alloys Open
In this study, we report the electronic and chemical structure of supported GaRh alloys as model systems for the active phase in supported catalytically active liquid metal solutions (SCALMS). We prepared a series of gallium–rhodium sample…

Isolated Rh atoms in dehydrogenation catalysis Open
Isolated active sites have great potential to be highly efficient and stable in heterogeneous catalysis, while enabling low costs due to the low transition metal content. Herein, we present results on the synthesis, first catalytic trials,…

Supraparticles for Bare‐Eye H<sub>2</sub> Indication and Monitoring: Design, Working Principle, and Molecular Mobility Open
Indicators for H 2 are crucial to ensure safety standards in a green hydrogen economy. Herein, the authors report micron‐scaled indicator supraparticles for real‐time monitoring and irreversible recording of H 2 gas via a rapid eye‐readabl…
Highly Effective Propane Dehydrogenation Using Ga–Rh Supported Catalytically Active Liquid Metal Solutions Open
Our contribution demonstrates that rhodium, an element that has barely been reported as an active metal for selective dehydrogenation of alkanes becomes a very active, selective, and robust dehydrogenation catalyst when exposed to propane …
Low‐Temperature Synthesis of Oxides in Ionic Liquids: Ozone‐Mediated Formation of Co<sub>3</sub>O<sub>4</sub> Nanoparticles Monitored by In Situ Infrared Spectroscopy Open
For most functional oxides, structure‐selective synthesis is the key for the task‐specific production of nanomaterials. Herein, the low‐temperature synthesis in ionic liquids (ILs) is an attractive strategy to produce nanomaterials which a…
Deformation induced pseudomagnetic fields in complex carbon architectures Open
We show that the physics of deformation in $\\alpha$-, $\\beta$-, and\n$6,6,12$-graphyne is, despite their significantly more complex lattice\nstructures, remarkably close to that of graphene, with inhomogeneously strained\ngraphyne descri…
Operando DRIFTS and DFT Study of Propane Dehydrogenation over Solid- and Liquid-Supported Ga<sub><i>x</i></sub>Pt<sub><i>y</i></sub> Catalysts Open
Supported catalytically active liquid metal solutions (SCALMS) represent a class of catalytic materials that have only recently been developed, but have already proven to be highly active, e.g., for dehydrogenation reactions. Previous stud…
