Article Synopsis
- The study focuses on how immobilizing GaPt liquid metal alloy droplets on specially designed supports can enhance catalytic performance by preventing droplet merging and losing active surface area.
- Researchers used supraparticle (SP) supports with varying pore sizes to investigate how these sizes influence the stability of GaPt droplets during propane dehydrogenation reactions.
- Results showed that larger pore sizes led to better stability of the GaPt droplets, reducing deactivation rates and confirming successful immobilization without changes before and after the reaction, highlighting the importance of pore size in catalyst support design.*
A novel GaPt-based supported catalytically active liquid metal solution (SCALMS) material is developed by exploiting the suprabead concept: Supraparticles, micrometer-sized particles composed of nanoparticles assembled by spray-drying, are bonded to millimeter-sized beads. The suprabeads combine macroscale size with catalytic properties of nanoscale GaPt particles entrapped in their silica framework.
