Facile and Environmentally Friendly Synthesis of GaO/MFI Catalysts for Propane Dehydrogenation.

A GaO-based catalyst is recognized as a promising catalyst for dehydrogenation of light alkanes. Conventionally, impregnation and calcination are necessary processes for the loading of GaO. However, the incomplete impregnation of gallium salt solution would generate wastewater, and the calcination for the dissociation of gallium salt would release harmful gases, such as SO, NO, and HCl.
