Formic acid oxidation reaction (FAOR) was studied using different platinum-zeolites hybrid catalysts. The catalysts were prepared by addition of two forms the ZSM-5 zeolite (ZSM-5-H+ and ZSM-5-NH4+) to an ink containing Vulcan carbon support Pt nanoparticles (NPs). TEM images demonstrate a proper mixture components in good dispersion NPs mainly over carbon. Both zeolites (ZSM-5-NH4+ ZSM-5-H+) a...

The effect of an alumina-based binder on the structure a commercial Fe-ZSM-5 catalyst has been investigated. Several ex-situ characterization techniques were used to show that in formulation allows obtaining material possesses improved features terms Fe species dispersion, framework Al content and acidity. UV–Vis X-ray absorption spectroscopy showed extent agglomeration extruded was significant...

Mesoporous ZSM-5 prepared by alkaline treatment was demonstrated as an efficient catalyst for the cellulose hydrolysis in ionic liquid (IL), affording a high yield of reducing sugar. It was demonstrated that mesoporous ZSM-5 (SiO₂/Al₂O₃ = 38) had 76.2% cellulose conversion and 49.6% yield of total reducing sugar (TRS). In comparison, the conventional ZSM-5 had a mere 41.3% cellulose conversion ...

Large-scale density functional theory calculations (DFT) found various types of binding of an unsaturated hydrocarbon (C2H2 and C2H4) to a ZSM-5 zeolite extraframework copper cation. We employed the DFT calculations based on the B3LYP functional to obtain local minima of an unsaturated hydrocarbon adsorbed on one or two copper cations embedded inside ZSM-5, and then compared their stabilization...
