- Abstract
- Substitution of oxygen by nitrogen in galloaluminophosphate oxides leads to compounds, with properties and applications improved as compared to the oxide. The structural and electronic changes induced by the anionic substitution of oxygen by nitrogen on those amorphous compounds have been studied by XAS. The investigation of the EXAFS and XANES data have allowed us to highlight some structural changes; in particular the existence of mixed tetrahedra XOxNy (x being P, Al or Ga) have been demonstrated. Such a study is helpful in understanding the variations in the surface acido-basic properties of these compounds.
