| Abstract: | The protonic acid sites are formed from hydrogen molecules on Pt/SO4
2--ZrO2 , and the resulting protonic acid sites act as active sites for acid-catalyzed reactions. Promotion of molecular hydrogen on the activities is observed not only for the Pt/SO4
2--ZrO2, but also for the other catalysts such as a physical mixture of Pt/SiO2 and H-ZSM5, and Co.Mo/SiO2-/Al2O3 . A molecular hydrogen-originated protonic acid site is proposed as a widely applicable concept for an active site on solid acid catalysts. |
