Abstract The Sabatier principle is widely explored in heterogeneous catalysis, graphically depicted volcano plots. most desirable activity located at the peak of volcano, and further advances past this optimum are possible by designing a catalyst that circumvents limitation entailed principle. Herein, density functional theory calculations, we discovered an unusual on high entropy alloy (HEA) surface, distinguishing “just right” (Δ G H* = 0 eV) hydrogen evolution reaction (HER). A new...
Selective catalytic hydrotreatment of lignin-derived phenols and dimeric ethers into alkanes is crucial for utilization lignin its fragments.
The application of 2D materials in catalysis has great potential, opportunities, and challenges. dual roles (catalysts supports) determine different strategies for rational design 2D-based catalysts.
This study unravels the catalytic effects of adjacent protons in redox catalysis bifunctional Keggin-type phosphomolybdic acid clusters (H3PMo12O40). Isolated sites (O*) and Brønsted acid-redox site pairs (OH/O*) catalyze methanol oxidative dehydrogenation (ODH), a reaction, via identical elementary steps formation kinetically relevant [HOCH2···H···O*]‡ [OH···HOCH2···H···O*]‡ transition states, but with different kinetic requirements, established from selective inactivation, product...
Methylacrolein (MAL) is traditionally synthesized from propanal and formaldehyde via the Mannich reaction instead of aldol in homogeneous catalytic systems due to undesired self-condensation propanal. Herein, direct synthesis MAL trioxane was realized on an acid–base bifunctional Cs-P/γ-Al2O3 catalyst, which exhibited good stability could be prepared a large scale with 54.5% yield 100% selectivity. The influence P elements structure properties even selectivity MAL, compared Cs/γ-Al2O3,...
In order to obtain the regularities of physicochemical properties hydroxy protic ionic liquids (PILs) and broaden their potential application, a series 2-hydroxyethylammonium sulfonate-based PILs were synthesized through proton transfer reaction characterized by NMR FT-IR elemental analysis. Their phase behavior (Tm) initial decomposition point (Td) differential scanning calorimetry (DSC) thermogravimetric analysis (TGA), respectively. Meanwhile, density (ρ), viscosity (η) electrical...
This study unravels the catalytic rate couplings and mechanistic similarities differences in C–O bond scission formation catalysis methanol trioxane, catalyzed by Brønsted acidic polyoxometalate clusters (POM). Turnovers of dehydration, trioxane decomposition, methanol–formaldehyde acetalization that form dimethyl ether (CH3O–CH3), formaldehyde (CH2O), dimethoxymethane (CH3O–CH2O–CH3), respectively, vary over six orders magnitude (308–423 K), yet these reactions share several common...
Hydrodeoxygenation (HDO) of lignin-derived phenols and dimeric ethers to biofuels has great significance for advanced utilization renewable lignocelluloses the future biobased economy. Herein, we find that deoxygenation process during model compound HDO could efficiently be catalyzed by low-cost protic ionic liquids under mild conditions. 2-Hydroxy-N-(2-hydroxyethyl)-N-methylethanaminium trifluoromethanesulfonate ([BHEM]CF3SO3) shows highest catalytic activity reaction with Rh/C as...
Abstract The treatment or upgrading of waste trifluoromethane (CHF 3 , R23), which has a significant greenhouse effect, is great importance in industry. Herein, series SO 4 2− /ZrO 2 ‐SiO catalysts with different Brønsted and Lewis acid site densities ratios were prepared for pyrolysis R23 to tetrafluoroethylene (C F TFE) hexafluoropropylene 6 HFP). effects impregnation concentration (NH ) on specific surface area, crystal phase, respectively demonstrated. sites observed have cooperative...
Kinetic interconnectivities of methanol oxidative dehydrogenation and dehydration are manifestation the underlying thermochemical/electronic correlations between redox Brønsted sites on bifunctional Keggin-type polyoxometalate (POM) phosphomolybdic acid clusters with their electronic properties perturbed by sodium cation exchange (HxNa3–xPMo, x = 3–0). As increases, activation free energies for elementary C–H scission in dehydrogenation, occurring at isolated (O*) or acid-redox site pairs...
