Abstract
The chemical states and coordination geometries of Ga species in Ga/H[Si,Al ]-beta (prepared by impregnation) and [Si,Ga]-beta (prepared by hydrotherma l synthesis) before and after in situ redox treatments were determined by G a Kedge X-ray absorption spectroscopy, and confirmed by density functional theory calculation.
