In this work, a theoretical study in conjunction with a spectroscopic analysis by FTIR were carried out in order to obtain molecular insights on the role of (CTA+)(≡SiO−) ion pair into the catalytic activity of [CTA+]–Si–MCM-41, ...

In this work, we analyzed the role of the interactions involved in the reaction mechanism for the transesterification of ethyl acetate and methanol on the pore mouth of [CTA+]-Si-MCM-41 catalyst. The Quantum Theory of Atoms ...

Ring opening of decalin was studied using Rh-Pd(x) catalysts supported on SiO2-Al2O3, prepared by coimpregnation with a variable total metallic content (x = 1, 1.5 and 2 wt%) while maintaining constant the Rh/Pd atomic ...

© 2017 Elsevier Inc. The genome of Methanosarcinales organisms presents both ADP-dependent glucokinase and phosphofructokinase genes. However, Methanococcoides burtonii has a truncate glucokinase gene with a large deletion ...

The catalytic behavior of bifunctional V2O5/MFI catalysts with acid and oxidizing properties was investigated for the gas-phase oxidehydration of glycerol. One of the main reaction products was acrylic acid, produced by ...

The influence of the supports (Al2O3, TiO2 and SiO2) on the activity and selectivity of Pt-Ir catalysts for the ring opening of decalin was studied. It was found that the properties of the supports strongly influence the ...

Conformational flexibility plays a critical role in enzyme function and is a key aspect in transitions from an open to a closed state induced by substrate binding and product release. Psychrophilic enzymes display a high ...
