The catalyst preparation route is well known to affect the copper loading and its electronic state, which influence the properties of the resulting catalyst. Electronic states of copper ions in copper-containing silicalites with the MFI-framework topology obtained by a solid-state transformation S (SST) were studied with using EPR, UV-Vis DR, XRD, H-TPR and chemical differentiating dissolution. They were compared with Cu-ZSM-5 and Cu-MFI (silicalite) prepared via the ion-exchange and incipient wetness impregnation.

- * Researchers studied the microbial communities in the oil site, identifying their genetic characteristics and metabolic pathways related to hydrocarbon degradation, revealing significant links between geochemical factors and microbial community structure.
- * The study concluded that geochemical parameters shape the composition and metabolic capabilities of these communities, with a predominant metabolic pathway for hydrocarbon oxidation, supporting the theory of abiogenic synthesis of Uzon’s hydrothermal petroleum.
The aim of this work was to study the one-pot synthesis of sorbitol via hydrolysis-hydrogenation of cellulose in the presence of Ru-containing composites based on HPWO supported on ZrO and NbO (Ru-PW/ZrO and Ru-PW/NbO). The main parameters impacted the reaction rate and yield of sorbitol, i.e.

It was shown that the optimum process temperature that prevents formic acid from destruction is 423 K. The studies were focused on the influence of the composition of heteropoly anions on the yield and selectivity of formic acid.
