Amorphous aluminosilicates are known for their excellent performance in (bio)ethanol dehydration ethylene production. Several studies showed that the homogeneous dispersion of Al amorphous is key to obtain active and stable catalysts. However, ensuring a high aluminosilicate matrix remains complicated task. Here, aerosol assisted sol-gel (AASG) process presented as facile one-step continuous production method towards highly aluminosilicates. We systematically examine effect aluminum loading...
Abstract Introducing organic groups into metal silicate catalysts and thus supposedly changing the surface hydrophobicity has been shown to enhance catalyst performance in various reactions. However, introduction does not unambiguously guarantee control. Therefore, a thorough characterization is necessary provide complete view of interaction between surface, reactants, products. Herein, an aluminosilicate with well‐dispersed Al atoms was prepared via non‐hydrolytic sol‐gel method. This...
Borane cluster-based porous covalent networks, named activated borane (ActB), were prepared by cothermolysis of decaborane(14) (nido-B10H14) and selected hydrocarbons (toluene, ActB-Tol; cyclohexane, ActB-cyHx; n-hexane, ActB-nHx) under anaerobic conditions. These amorphous solid powders exhibit different textural Lewis acid (LA) properties that vary depending on the nature constituent organic linker. For ActB-Tol, its LA strength even approaches commonly used molecular LA, B(C6F5)3. Most...
Hybrid materials based on metallosilicates are extensively studied for their enhanced catalytic performance. Introducing organic groups into metal silicate catalysts and thus supposedly change the surface hydrophilicity hydrophobicity has been shown to have an appreciable effect catalyst performance in various reactions, including epoxide ring opening reactions alcohol dehydration. However, sole introduction does not unambiguously guarantee control might lead porosity drop, acidity...

Synthesis of 1,3-butadiene (BD) from ethanol has experienced a true renaissance in recent years due to ecological and economic reasons. The open porosity number Lewis acid sites metal silicates (M = Zr, Ta) have been reported numerous studies as key factors enabling reaching high BD productivity. However, some microporous zeolites recently displayed very To gain deeper insight, we applied non-hydrolytic sol-gel (NHSG) – method well-known produce highly porous homogeneous the preparation...
