Abstract ：
The efficient utilization of hydrogen resources in H2S has aroused great attention in both resource utilization and environmental protection. Using H2S as a hydrogen resource donor for the reduction of nitrobenzene to aniline could be an effective method to replace H2. Herein, we fabricated the porous flower-like CoNi-LDO catalyst through facile morphology control engineering, which utilizes DMF as an intercalating agent to influence the structure and properties. Endowed with abundant electron-rich oxygen vacancies and enhanced basic sites capacity, the as-designed CoNi-D catalyst exhibits considerable aniline selectivity (96 %) and high catalytic stability over seven cycles at 110 degrees C. The potential single H-induced dissociation pathway for the reduction of nitrobenzene to aniline by H2S was explored using in situ FT-IR analysis. The present study could provide a feasible strategy for designing catalysts for the high-value utilization of H2S.

Abstract ：
Graph structure is widely used in the field of multi-view learning. Hypergraph which is a kind of extension of graph can capture the higher-order relationships of nodes in a better way. However, most existing hypergraphbased models are based on the assumption that hypergraph structures are readily available, which is untenable in most cases. In order to alleviate this problem, we propose the learnable unified hypergraph dynamic system framework, a novel approach in unified cross-view hypergraph structure generation tailored for multi-view semi-supervised classification. Specifically, we introduce four strategies for unified cross-view hypergraph generation and propose a mechanism for generating learnable unified cross-view hypergraph. Furthermore, we utilize a dynamic diffusion model to dynamically learn unified hypergraph structure which can achieve better performance in multi-view semi-supervised classification tasks. Extensive experimental results on various real datasets show that the proposed method outperforms other state-of-the-art multi-view algorithms.

Abstract ：
The limited degradability and high production costs associated with traditional epoxy resin pose obstacles to its sustainable development. In this study, hybrid material of epoxidized soybean oil-derived epoxy resin (ESOR) and hydrothermal carbon microspheres (HTCs) was designed. Investigations confirmed the presence of diverse oxygen-containing groups on the HTCs, with the carboxyl content specially increased through air activation, which also increased the specific surface area. These alterations enhanced the interfacial interactions between HTCs and ESOR. As a result, the optimized composite exhibited the most notable tensile strength of 3.91 MPa, approximately 22.6 % higher than that of the pure ESOR. Importantly, the incorporation of the air-activated HTCs, which had the water holding and cation exchange capabilities, significantly enhanced the degradability of the ESOR matrix, about 68.3 wt% and 100.0 wt% of the ESOR decomposed respectively from 5HTC300/ESOR and 7 HTC300/ESOR immersed in 0.5 wt% NaOH for 15 day, without the use of organic solvents. While applying the composite materials in coated fertilizers with a 0.5 wt% paraffin outer layer, the best one can slowly release 47.7 % P in 20 days.

Abstract ：
Previous N-glycosylation approaches have predominately involved acidic conditions, facing challenges of low stereoselectivity and limited scope. Herein, we introduce a radical activation strategy that enables versatile and stereoselective N-glycosylation using readily accessible glycosyl sulfinate donors under basic conditions and exhibits exceptional tolerance towards various N-aglycones containing alkyl, aryl, heteroaryl and nucleobase functionalities. Preliminary mechanistic studies indicate a pivotal role of iodide, which orchestrates the formation of a glycosyl radical from the glycosyl sulfinate and subsequent generation of the key intermediate, a configurationally well-defined glycosyl iodide, which is subsequently attacked by an N-aglycone in a stereospecific SN2 manner to give the desired N-glycosides. An alternative route involving the coupling of a glycosyl radical and a nitrogen-centered radical is also proposed, affording the exclusive 1,2-trans product. This novel approach promises to broaden the synthetic landscape of N-glycosides, offering a powerful tool for the construction of complex glycosidic structures under mild conditions. A versatile and stereoselective N-glycosylation has been developed using glycosyl sulfinates under basic conditions. Mechanistic studies indicate the transformation involves a key glycosyl radical species, which can directly couple with a nitrogen-centered radical. An alternative route involving the coupling of glycosyl and iodine radicals, followed by an SN2 reaction with the resultant glycosyl iodide to give the N-glycoside, is also demonstrated. image

Abstract ：
Developing highly efficient catalysts for the transformation of hydrogen sulfide (H2S) pollutants into value-added products is crucial for both fundamental catalytic research and industrial chemistry. Herein, ferrititanate nanosheets (H0.8Ti1.2Fe0.8O4, denoted as NS-HTFO) exfoliated from lepidocrocite-type titanates are employed for the first time to catalyze the conversion of H2S to elemental sulfur. Collective experimental characterizations reveal that the as-designed NS-HTFO catalyst possesses ultrathin 2D structure and a large specific surface area, featuring abundant oxygen vacancies. Compared with its sandwich-like precursor of K0.8Ti1.2Fe0.8O4 (denoted as L-KTFO), the NS-HTFO catalyst displays notably enhanced desulfurization activity, achieving 100 % H2S conversion and over 93 % sulfur selectivity at temperatures ranging from 90 to 270 degrees C. Moreover, no significant decline in sulfur yield is observed over the course of a 100-hour evaluation, showing outstanding breakthrough sulfur capacity up to 4163 mg/gcat. This performance exceeds that of most recently reported catalysts. The possible catalytic mechanism for H2S-to-S selective oxidation over the NS-HTFO catalyst has also been investigated.

Abstract ：
The conversion of H2S to high-value-added products is appealing for alleviating environmental pollution and realizing resource utilization. Herein, we report the reduction of nitrobenzene to aniline using waste H2S as a "hydrogen donor" over the catalyst of FeCeO2-delta with abundant oxygen vacancies (Ov), especially an asymmetric oxygen vacancy (ASOv). The electron-rich nature of the ASOv sites facilitates electron transfer to the electron-deficient nitro group, promoting the adsorption and activation of Ph-NO2 through the elongation and cleavage of the N-O bond. Benefiting from the formation of abundant ASOv sites, the resulting FeCeO2-delta achieves an impressive 85.6% Ph-NO2 conversion and 81.9% Ph-NH2 selectivity at 1.5 MPa and 90 degrees C, which surpasses that of pure CeO2 with flower and rod morphologies. In situ FT-IR measurements combined with density functional theory calculations have elucidated a plausible reaction mechanism and a rate-limiting step in the hydrogenation of Ph-NO2 by H2S.

Abstract ：
The use of bio-oil-based polymers in fertilizer coatings has drawn significant academic interest. However, the challenge remains to eliminate toxic chemicals while enhancing comprehensive properties. This study focused on synthesizing a degradable polymer from epoxidized soybean oil (ESO) without organic solvent at low temperature (120 degrees C), accomplished through a modified curing agent (MCA). This MCA was made of an acidic eutectic mixture of phthalic anhydride (PA) and its glycerides, produced from inexpensive, low-toxic phthalic anhydride and glycerol. The process utilized a small quantity of zinc acetate (0.5 wt%) to facilitate the formation of phthalic triglyceride in the MCA and mitigate PA sublimation, resulting in the enhanced cross-link degree, superior mechanical properties and hydrophobicity of the ESO-based resin (ESOR). Under optimal preparation conditions, the solvent-free ESOR-coated fertilizer exhibited an extended longevity of 53 days, with an 80 % phosphorus release. This coating material can undergo hydrolytic degradation in soil and in-situ conversion into carboxylates. These findings hold significant potential for advancing the applications of ESOR in green and sustainable agriculture.

Abstract ：
Catalytic hydrolysis was considered as an efficient technology to remove carbonyl sulfide (COS). The introduction of oxygen vacancy (Ov) is a promising strategy to improve the catalytic performance of COS hydrolysis by promoting the adsorption and activation of reactants. Herein, we reported a Cu-doped TiO2 nanoflower with abundant oxygen vacancies for COS hydrolysis. The Cu species successfully entered the crystal lattice of TiO2 and induced more oxygen vacancies than pure TiO2. The Ov sites can effectively reduce the adsorption and activation energy of COS and H2O. Benefiting from the ample Ov sites, the resulting CuTiO2-8-F achieved nearly 100 % COS conversion at 70 degrees C and 93.5 % H2S yield at 130 degrees C, which is better than that of pure TiO2. Furthermore, in situ FT-IR measurements and density functional theory (DFT) calculations were performed to reveal the reaction pathway in COS hydrolysis.

Abstract ：
Carbonyl sulfide (COS) is commonly found in conventional fossil fuels, such as nature gas, oil-associated gas, and blast-furnace gas, and its untreated emission not only corrodes pipelines and poisons catalysts but will also inevitably pollute the environment and endanger human health. Catalytic hydrolysis is recognized as the most promising strategy to eliminate COS because it can be performed under mild reaction conditions with a high removal efficiency. Notably, alkali metals promote catalytic COS hydrolysis over Al2O3 owing to their electron donor properties, basicity, and electrostatic adsorption. However, despite the significant attraction of using potassium-promoted Al2O3 (K2CO3/Al2O3) as conventional catalysts for COS hydrolysis, the mechanism of COS hydrolysis over K2CO3/Al2O3 remains unclear and is controversial owing to the complex composition of the K species. In this study, commercial Al2O3 modified with potassium and sodium salts were synthesized using the wet impregnation method and characterized by various techniques. Based on the results of the activity measurements, the K2CO3-, K2C2O4-, NaHCO3-, Na2CO3-, and NaC2O4-modified catalysts had a positive effect on COS hydrolysis. Among them, the K2CO3/Al2O3 catalyst exhibited the highest COS conversion. Notably, the K2CO3/Al2O3 catalyst exhibited an excellent catalytic performance (-93%, 20 h), which is significantly better than that of pristine Al2O3 (-58%). Furthermore, this study provides strong evidence for the role of H2O during catalytic hydrolysis over K2CO3/Al2O3 using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and X-ray photoelectron spectroscopy (XPS). The in situ DRIFTS analysis revealed that hydrogen thiocarbonate formed as an intermediate during COS hydrolysis over K2CO3/Al2O3. Meanwhile, the XPS findings suggested that sulfates and elemental sulfur accumulated on the catalyst surface, which may have contributed to catalyst poisoning. Additionally, the effect of water vapor content in the reaction pathway of COS hydrolysis over K2CO3/Al2O3 was investigated. The presence of excess water resulted in a reduction in catalytic activity owing to competitive adsorption between H2O and COS molecules on the catalyst surface. The enhancement in the catalytic activity over K2CO3/Al2O3 may be attributed to the formation of HO-Al-O-K interfacial sites. More importantly, all the catalysts were used under industrially relevant conditions, which provides valuable theoretical guidance for practical applications in the future. Thus, this detailed mechanistic study reveals new insights into the roles of the interfacial K co -catalyst, which provides a new opportunity for the rational design of stable and efficient catalysts for COS hydrolysis.
