Acidic nanomaterials (TiO2, ZrO2, and Al2O3) are coke storage components that reduce the deactivation of the Pt–Sn/γ-Al2O3 catalyst in propane dehydrogenation

Pt–Sn/γ-Al₂O₃ catalysts were physically mixed with various nanostructured metal oxides (TiO₂, ZrO₂, and Al₂O₃) and investigated as catalysts for propane dehydrogenation at 550 °C and atmospheric pressure.
