Reversible transformation of sub-nanometer Ga-based clusters to isolated [4]Ga(4Si) sites creates active centers for propane dehydrogenation

This work describes how a propane dehydrogenation catalyst with isolated [4] Ga (4Si) sites can be prepared from silica-supported sub-nm gallia clusters containing [4] Ga (Ga) and [6] Ga (Ga) sites.
