Dispersion assessment of H3PMo12O40 supported on TiO2 through in situ IR upon pyridine adsorption

Alixandre Magerat, Laetitia Valentin, Alexandre Vimont, Sophie Hermans, Eric M Gaigneaux, Josefine Schnee

Keggin heteropolyacids (HPAs) are powerful catalytic materials because of their particularly high acid strength. Dispersing them on a support is a commonly adopted strategy to overcome their low specific surface area and increase their recoverability. In this regard, their dispersion needs to be…
