A novel functionalized MOF material, Brönsted acidic ionic liquid (BAIL) confined inside well-defined MIL-101 nanocages, was developed for the first time based on tandem post-synthetic strategy. The catalytic performance of BAIL in material evaluated by using acetalization benzaldehyde with glycol as a probe reaction. resulting BAIL/MIL-101 exhibited superior performance, which is mainly due to combination advantageous merits catalyst desirable microenvironment nanocages.
This critical review presents the fundamentals, challenges, and outlooks in MTHMs according to state-of-the-art progress first-hand experience.
PdCl<sub>2</sub> immobilized on CuBTC with the aid of ILs shows an enhanced catalytic performance in cyclohexene oxidation due to Pd–Cu cooperative catalysis and stabilization Pd(<sc>ii</sc>).
Abstract Regulating reaction pathway of glucose isomerization and epimerization is essential for production high‐fructose corn syrup rare sugars. Herein, we show a molecular‐level observation on transformation using metal‐organic frameworks (MOFs) with single‐site active centers (SSACs) as heterogeneous catalysts. It found that Lewis acidic Cr (III) sites MIL‐101 prefer to catalyze glucose‐to‐fructose in either water or methanol solvent. Elevating temperature can promote glucose‐to‐mannose...
The Fe-doped silicalite-1 zeolite as a matrix was employed to implant GaN nanocrystallites via combined wet impregnation with in situ nitridation method. Direct spectroscopic evidences under vacuum unraveled that the incorporation of isolated framework Fe atoms could cause generation more interior silanols and especially hydrogen-bonded groups silanol nests, where solvated Ga3+ ions urea an N2 atmosphere at high temperatures were transformed into highly dispersed embedded simultaneously...
The intrinsic effect of the support microstructure on catalytic function VO<sub>x</sub>/Al<sub>2</sub>O<sub>3</sub>in oxidative dehydrogenation propane (ODHP) was studied.
A series of SiO2-supported silicotungstic acid (STA/SiO2) catalysts were prepared by the incipient impregnation method and utilized in dehydration ethanol to ethylene. The characterized through X-ray diffraction (XRD), N2 physical adsorption, transmission electron microscopy (TEM), fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), pyridine-adsorbed FTIR (Py-FTIR), Raman spectroscopy, thermogravimetry/differential scanning calorimetry (TG/DSC). influence loading amount...
GaN‐containing titanosilicate catalysts were used for the first time oxidative dehydrogenation (ODH) of n ‐butane at a relatively low reaction temperature (460 °C). Commercially available GaN powder with wurtzite crystal structure showed superior reactivity and stability ODH ‐butane. The catalytic property catalyst strongly depends on particle size. effects weight percentage size performance are investigated in fixed bed reactor. Based physicochemical properties characterized via TEM, DLS, N...
We report an efficient procedure for the synthesis of pillared MWW zeolites (MCM-36) via integrating intercalation and hydrolysis tetraethyl orthosilicate (TEOS) into one step. Specifically, two specially selected surfactants with more hydrophilicity instead conventional swelling agent cetyltrimethylammonium bromide (CTAB) were employed to increase interlayer wetting ability water content. The resultant TEOS occur concurrently in a confined microenvironment enriched basic hexamethyleneimine...
Facile synthesis of mesoporous mordenite with excellent catalytic performance for alkylation benzene 1-dodecene was achieved by using an organosilane surfactant as assistant directing agent.
We report a facile preparation of nanosized mordenite (MOR) with different morphologies, i.e., crystals and nanoplatelets. Specifically, MOR (30–80 nm) in three dimensions (3D) were synthesized the absence long-chain organic surfactant as crystal growth-inhibiting agent by simply decreasing mole ratio Na2O/SiO2 synthesis gel. Furthermore, nanoplatelets 50–100 nm thickness using cooperation structure-directing agents (SDAs) tetraethylammonium hydroxide (TEAOH) hexamethyleneimine (HMI), where...
To develop an efficient solid acid catalysts for the Friedel-Crafts alkylation reaction, especially involving bulky molecules, direct synthesis of hierarchical nanocrystalline β zeolites were achieved by using amphiphilic organosilane ([(CH3O)3SiC3H6N(CH3)2C18H37]Cl, TPOAC) as collaborative structure-directing agent (SDA). The growth evolution crystals and influence TPOAC/SiO2 molar ratio on mesoporous structure, crystal size, acidic properties investigated discussed in detail....
