“…To address the pressing question of the Lewis acidityaluminum structure relationship, we turned to MOR zeolites. Mordenite is widely used as a heterogeneous catalyst and support in extensively researched reactions, such as hydroisomerization of hydrocarbons, 30 methane to methanol, 31 and selective catalytic reduction. 32 Five MOR zeolite samples, with different Si/Al ratios given in brackets, were used in this study.…”

“…4 Protonic zeolites are extensively used for several reactions, in particular, cracking, alkylation, and isomerization. [5][6][7] Apart from Brønsted acid sites, certain aluminum species in zeolites possess Lewis acidic character. Lewis acidic aluminum (Figure 1b) plays a pivotal role not only in traditional cracking reactions, but also in salient biomass valorization reactions, 8,9 which include the conversion of trioses to alkyl lactates, 10 and cellulose to glucose.…”

“…Among many metals, rhenium is known for its ability to catalyze hydrogenolysis of heteroatomic X–C bonds and as a selective hydrogenation catalyst. It is also able to promote reactions involving C–C and aromatic C–H cleavages . Another remarkable property of rhenium oxide is its ability to reduce selectively carboxyl groups without affecting the aromatic ring …”

“…As mentioned above, rhenium is typically used in concert with a second noble metal such as ruthenium, platinum, and palladium, both deposited over a proper support (carbon, silica, and alumina). Rhenium promotes platinum/carbon catalysts for glycerol conversion, which suggests that its presence facilitates hydrogenolysis of the C–O bonds due to its ability to preferentially bond hydroxyl groups. , Then, these species will react in the second step with hydrogen dissociatively adsorbed and activated on the second noble metal, , resulting in an enhancement of the activity and selectivity . The Lewis acid effect exerted by rhenium in the hydrogenolys of oxygenated compounds has also been demonstrated by the enhancement induced in the selectivity of the bimetallic rhenium–ruthenium catalyst …”
