Syngas conversion by Fischer-Tropsch synthesis (FTS) is characterized a wide distribution of hydrocarbon products ranging from one to few carbon atoms. Reported here that the product selectivity effectively steered toward ethylene employing oxide-zeolite (OX-ZEO) catalyst concept with ZnCrOx -mordenite (MOR). The alone reaches as high 73 % among other hydrocarbons at 26 CO conversion. This significantly higher than those obtained in any direct syngas or multistep process methanol-to-olefin...
Magnesium alloys, the advanced lightweight structural materials, have been successfully applied in manufacturing field. Unfortunately, their poor corrosion resistance restrains potential wide applications. In this work, anti-corrosion coatings were fabricated via in-situ growth of inhibitors intercalated magnesium-aluminum layered double hydroxide (Mg–Al LDH) on AZ31 magnesium alloy and then post-sealing it by a super-hydrophobic coating. SEM, XRD, EDS, FTIR, XPS contact angle test conducted...
Abstract Despite significant efforts towards the direct conversion of syngas into liquid fuels, selectivity remains a challenge, particularly with regard to high‐quality gasoline high octane number and low content aromatic compounds. Herein, we show that zeolites 1D ten‐membered‐ring (10‐MR) channel structures such as SAPO‐11 ZSM‐22 in combination zinc‐ manganese‐based metal oxides (Zn Mn b O x ) enable selective synthesis gasoline‐range hydrocarbons C 5 –C 11 directly from syngas. The...
Cellulose dissolution is a worldwide issue in the production industry. Especially, development of highly efficient and green cellulose solvents has been considered as key factor to restrict broad application different industries. In this study, chloride salts, such LiCl, ZnCl2, CaCl2, FeCl3, with water amounts were used investigate driving force dissolution. The superfast ZnCl2·3H2O FeCl3·6H2O was successfully achieved within 5–20 min, which confirmed by results polarized light microscopy....
Despite wide studies demonstrating the versatility of metal oxide-zeolite (OXZEO) catalyst concept to tackle selectivity challenge in syngas chemistry, active sites oxides and mechanism CO/H2 activation remain be elucidated. Herein, we demonstrate experimentally role Cr zinc–chromium unveil visually, for first time, CO employing scanning transmission electron microscopy-electron energy loss spectroscopy using volumetric density surface carbon species as a descriptor. The ZnCr2O4 spinel with...
Defect engineering critically influences metal oxide catalysis, yet controlling coordinatively unsaturated sites remains challenging due to their inherent instability under reaction conditions. Here, we demonstrate that high-flux argon ion (Ar+) irradiation above recrystallization temperatures generated well-defined Zn (CUZ) on ZnO(101̅0) surfaces exhibited enhanced stability and activity for CO hydrogenation. Combining low-temperature scanning probe microscopy, ambient pressure X-ray...
Although ketene has been proposed to be an active intermediate in a number of reactions including OXZEO (metal oxide-zeolite)-catalyzed syngas conversion, dimethyl ether carbonylation, methanol hydrocarbons, and CO2 hydrogenation, its chemistry reaction pathway over zeolites are not well understood. Herein, we study the transformation gasoline range hydrocarbons molecular sieve H-SAPO-11 by kinetic analysis, situ infrared spectroscopy, solid-state nuclear magnetic resonance spectroscopy. It...
Formation and evolution of active hydrogen species from H2 on a metal oxide is great importance in many hydrogenation reactions, while understanding the nature surface remains challenge. Herein, high-vacuum-based transmission infrared spectroscopy coupled with temperature-programmed desorption has been applied to study over ZnO ZnCrOx catalysts. We show that D2 dissociates readily form Zn–D O–D at 153 K, simultaneous occurs 223 K. This corroborates reversible dissociation recombination ZnO....
Layered double hydroxides (LDHs) are attracting intense research interests as methyl orange (MO) adsorbent due to the unique anionic exchange ability. Herein, ultrasmall NiAl LDHs with Cl– intercalation were prepared by a facile method combining hydrothermal acid salt treatment. As result, as-prepared displayed favorable removal performance toward MO from aqueous solution negligible carbonate contamination and nanosheets (about 50 nm). The maximum experimental theoretical adsorption...
Despite significant progress achieved in Fischer-Tropsch synthesis (FTS) technology, control of product selectivity remains a challenge syngas conversion. Herein, we demonstrate that Zn2+ -ion exchanged ZSM-5 zeolite steers conversion selectively to ethane with its reaching as high 86 % among hydrocarbons (excluding CO2 ) at 20 CO NMR spectroscopy, X-ray absorption and fluorescence indicate this is likely attributed the highly dispersed Zn sites grafted on ZSM-5. Quasi-in-situ solid-state...

Abstract Syngas conversion by Fischer–Tropsch synthesis (FTS) is characterized a wide distribution of hydrocarbon products ranging from one to few carbon atoms. Reported here that the product selectivity effectively steered toward ethylene employing oxide‐zeolite (OX‐ZEO) catalyst concept with ZnCrO x ‐mordenite (MOR). The alone reaches as high 73 % among other hydrocarbons at 26 CO conversion. This significantly higher than those obtained in any direct syngas or multistep process...
NMR experiments reveal a mechanism of syngas conversion in which CO reacts with OCH 3 on the oxide surface, generating ketene intermediates, can either form acetate or diffuse into zeolite.

Understanding the complex relationships among molecular structures, weak solute–solvent interactions, and dissolving affinity is fundamentally important to successfully identify potential solvents from a large chemical space for diverse absorption capture separation. In this study, series of compounds including alkanolamines, amines with cyclic substituents, etheramines, polyamines, sulfonamides, several commercial physical were selected methyl mercaptan (MeSH) was used as model...
Mordenite (MOR) zeolite is known to possess a 12-membered ring (12 MR) and 8 MR channels, which are interconnected by side pockets. Hyperpolarization (HP) 129Xe NMR reveals new Xe adsorption site in addition the usual 12 main channels Different guest molecules exhibit explicitly site-selective on different sites of MOR, as demonstrated situ continuous-flow HP studies. For example, methanol prefers adsorb while water this connecting channel pocket. Furthermore, reduces pore size free mean...
