Atomic-scale changes of silica-supported catalysts with nanocrystalline or amorphous gallia phases: implications of hydrogen pretreatment on their selectivity for propane dehydrogenation

This work explores how H(2) pretreatment at 550 °C induces structural transformation of two gallia-based propane dehydrogenation (PDH) catalysts, viz. nanocrystalline γ/β-Ga(2)O(3) and amorphous Ga(2)O(3) (GaO(x)) supported on silica (γ-Ga(2)O(3)/SiO(2) and Ga/SiO(2), respectively) and how it affect...
