“…However, Ru/HZSM-5 catalyst has limitations that hinders its application. In a previous study conducted by our group, 10 we found that the Ru/HZSM-5 catalyst demonstrated good performance in the catalytic combustion of VC. However, its activity did not improve significantly compared to other catalysts reported in the literature.…”

“…The peaks between 100–250 °C were related to the desorption of NH 3 on weak acid sites, while the peaks above 250 °C corresponded to strong acid sites. 10 The weak acid was derived from isolated silanol and extra-framework Al species, and the strong acid was derived from the Si(OH)Al groups. 37,38 Ru/HZSM-5 catalyst possessed abundant weak and strong acid sites (Table S1†).…”
