Abstract ：
There is a particular demand to explore low-volatility and structurally tunable absorbents for efficiency, selectivity and reversibility in capturing H2S. For the first time, the performance of deep eutectic solvents (DESs) composed of 1-ethyl-3-methylimidazolium chloride ([Emim]Cl) and acetamide (AA) were examined as physical absorbents for H2S capture. The physical properties of [Emim]Cl-AA DESs, and solubilities of both H2S and CO2 in them were measured. Relevant experimental results demonstrated that the solubilities of H2S in [Emim]Cl-AA DESs (1.1 mol/kg at 298.2 K and 1.023 bar) significantly exceed those of CO2 (0.040 mol/kg at 298.2 K and 1.027 bar). [Emim]Cl-AA DESs exhibit higher H2S solubilities and superior ideal H2S to CO2 selectivities (e.g., the ideal H2S/CO2 selectivity of [Emim]Cl-AA (1:0.5) is 28.5 at 298.2 K) than those physical absorbents ever reported. The recyclability of [Emim]Cl-AA DESs for H2S selective capture was also evaluated, which was found to be very stable in ten continuous absorption and regeneration cycle experiments. The mechanism of H2S capture by [Emim]Cl-AA DESs was finally illustrated at the molecular level with the support of theoretical calculations. © 2024 Elsevier B.V.

Abstract ：
The efficient deoxygenation of renewable biolipids into liquid alkanes within the diesel range is a key protocol for producing high-quality biofuels. In this work, the conversion of methyl palmitate and raw palm oil were accomplished utilizing a bifunctional catalyst of Ni catalysts supported on B2O3-ZrO2 under solvent-free conditions. Among various Ni loading ratios investigated, the catalyst featuring a 10 % Ni loading achieved 100 % conversion of methyl palmitate and 84.4 % of liquid yield, with approximately 65 % being C15 alkanes. Additionally, more than 91 % of hydrocarbons were also generated from raw palm oil. These results can be attributed to the synergistic interplay between the acid sites, following B2O3 modification, and the presence of Ni species. Furthermore, the analysis of product distribution, gas product detection and the kinetics calculation strongly supports that the deoxygenation process of methyl palmitate primarily follows the hydrodecarbonylation route, leading to the predominant formation of C15 alkane. © 2024

Abstract ：
The design of novel practical catalysts is critical for the blossoming of biodiesel green-energy, in which Mo-based catalysts are of particular interest. In this work, an in-situ synthesis method was proposed to obtain a combo Mo-based ionic liquid and SAPO-11 catalyst. The catalyst presents both highly dispersed MoS2 as hydrodeoxygenation active sites and acidic sites for isomerization. MoS2 with a few fine layers can be identified based on TEM images and the Bronsted acid sites are dominant based on Pyridine-IR analysis. A great performance of MoS2/C(8)min-15 %SA can be obtained under optimized reaction conditions with 100 % conversion of methyl palmitate, 75.0 mol% hydrodeoxygenation to n-C-15-C-16, and 20.5 mol % isomerization to i-C-15-C-16. The structure and activity of the catalyst can be retained at least for 4 cycles. Thin layers and high sulfurization, large amount of Br & oslash;nsted acid sites, and suitable reaction conditions are key points to achieve a significant performance and avoid over cracking and deactivation. On basis of detected intermediates and kinetic data simulations, a complex reaction pathway was proposed and the specific k values for each elementary reaction were provided for the hydrodeoxygenation and isomerization of methyl palmitate.

Abstract ：
The effective separation of ammonia (NH3) has important implication for the conversion improvement and pollution control during the synthesis of NH3. In the present work, a novel kind of non-chloride deep eutectic solvents (DESs) were constructed from dihydroxybenzoic acids (DHBAs) and ethylene glycol (EG). The DHBA + EG DESs exhibit several weak acidic sites and hydrogen-bond sites, thus were proposed for NH3 separation. We found that the amounts of NH3 absorbed by DHBA + EG DESs are quite impressive, particularly at reduced pressures. The capacities can reach 5.64 and 11.69 mol/kg at 0.1 and 1 bar respectively, when the temperature of 298.2 K is considered. Besides, after five absorption-desorption cycles, the DHBA + EG DESs can preserve the excellent NH3 absorption performance. The DHAB + EG DESs can also selectively absorb NH3 from N2 and H2 in the mixed gas. The NH3 absorption mechanism of DHBA + EG DESs was further deeply illustrated by spectro-scopic techniques and theoretical calculations.

Abstract ：
Solid adsorbents with high NH3 separation performance and good stability are particularly important for industrial applications. In our work, few-layered hexagonal boron nitrides (h-BNs) were synthesized and proposed as a kind of solid adsorbent by utilizing the abundant Lewis acidic B atoms on h-BNs. The synthesized h-BNs were investigated for NH3 separation both experimentally and theoretically. It is found that the NH3 isotherms of h-BNs slightly deviate from the ideal profiles, suggesting that the h-BNs enable moderate interactions with NH3. At the pressure of 0.1 and 1 bar, the h-BNs can adsorb as much as 2.33 and 8.67 mmol/g of NH3, respectively. The h-BNs also demonstrate highly selective adsorption of NH3 from other gases such as N2, H2, and CO2, regardless of calculated ideal selectivities or breakthrough adsorption of mixed gases. The NH3 adsorption of h-BNs can be completely reversed, and the h-BNs also exhibit high oxidative resistance, which is of vital importance for the long-term application in industry. Density functional theory calculations and molecular dynamics simulations were further conducted to rationalize the effective separation of NH3 by h-BNs and disclose the underlying mechanism at the molecular level.

Abstract ：
Renewable fatty esters are a class of clean feedstock to produce high value-added fatty alcohols. Herein, the hydrogenation of methyl palmitate (MP) to hexadecanol over defect-rich Cu/m-ZrO2 catalysts was studied systematically. A series of Cu/m-ZrO2 catalysts with different concentrations of oxygen vacancies (Ovs) were fabricated by adjusting the calcination temperature of m-ZrO2 support. Among the catalysts, Cu/m-ZrO2-350 displays the highest Cu dispersion, the largest number of Cu0 sites and surface Ov concentration, which exhibits the best activity for MP hydrogenation. It gives the MP conversion of 94.6% and hexadecanol yield of 93.3% at 300 degrees C and 7.5 MPa of H2. Spectroscopic characterizations and theoretical calculations revealed that the highly dispersed Cu species and abundant Ov sites synergistically boost the hydrogenation of MP. Specifically, the Cu0 sites facilitate the heterolysis of H2, and the Ov sites contribute to the dissociation of MP. The synergistic effect of Cu species and Ov sites disclosed in this work provides deep insights into the design of catalysts for efficient conversion of fatty esters to fatty alcohols.

Abstract ：
Dispersed metal sulfides are promising catalysts for the hydroconversion of biolipids to produce second-generation biodiesel. In this work, oil-soluble Mo-based ionic liquids (ILs) were innovatively utilized as the precursors for in situ generation of MoS2 catalysts for the hydroconversion of biolipids. Taking methyl palmitate as the model compound, the excellent activity of in situ generated MoS2 from ionic liquid Mo-based precursors was obtained. The turnover frequencies (TOFs) reached up to 1.6 x 102 h-1 for methyl palmitate conversion and 83 h-1 for hexadecane (C16) yield at 320 degrees C and 0.5 h (42% conversion) under solvent-dilute conditions. The structures of in situ generated MoS2 catalysts were characterized to pro-vide explanations for the catalytic results. Based on the product distributions, the pathway of methyl palmitate hydroconversion was proposed, and the kinetics of methyl palmitate hydroconversion was analyzed in further detail. Applying the Mo-based ILs in the hydroconversion of methyl palmitate and palm oil under solvent-free condition also granted high conversions of feeds and selectivities of HDO products.(c) 2023 Elsevier Inc.

Abstract ：
In this work, an oil-soluble ionic liquid (IL) was combined with mixed metal oxide for in situ generation of bifunctional catalysts for slurry-phase heavy oil hydrocracking. The oil-soluble IL selected was trihexylmethylammonium molybdate ([N-6661](2)MoO4), and the mixed metal oxide selected was SiO2-ZrO2. The performance of using [N-6661](2)MoO4 and SiO2-ZrO2 for slurry-phase hydrocracking was examined systematically. It is found that the addition of SiO2-ZrO2 can significantly improve the conversion of residue to distillate and the gas and coke yields are also improved. The MoS2/SiO2-ZrO2 bifunctional catalysts in situ generated in the reaction system were collected for detailed characterizations. The MoS2 slabs are in a highly dispersed and sulfurized status in the matrix of SiO2-ZrO2, and there are also abundant acidic sites in resultant bifunctional catalysts. The kinetics of slurry-phase hydrocracking was further investigated to disclose the reaction routes for the conversion of residue and the role of adding SiO2-ZrO2 in promoting the hydrocracking reactions.
