SCALMS catalysis
Overview
Dissolving small amounts of catalytically active metal in a matrix metal (like Ga or In) results in alloys that become liquid under elevated reaction conditions. These supported catalytically active liquid metal solutions (SCALMS) represent a new class of heterogeneous catalysts, since they enable single-atom catalysis at dynamic gas-alloy interfaces. The high dynamics at this interface and the electronic properties of the surrounding matrix metal induce completely new activity and selectivity patterns in single atom catalysis (SAC). Moreover, such systems can be more stable compared to traditional heterogeneous counterparts, since coking is less likely to occur on highly dynamic surfaces.
