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 ：
Developing efficient strategies for converting hazardous hydrogen sulfide (H2S) waste into valuable products is crucial for mitigating environmental pollution and maximizing resource utilization. Herein, we present a novel approach for the selective reduction of nitroarenes (PhNO2) to arylamines (PhNH2) utilizing H2S as the hydrogen source. This process is facilitated by isolated Fe-Nx sites embedded within graphitic carbon nitride (Fe-CN-x) obtained through a polymerization assembly method. The Fe-CN-3 catalyst, in particular, achieves PhNO2 conversion of 92.0 % with PhNH2 selectivity of 95.8 % at 110 degrees C within 2 h reaction, outperforming the Bulk-CN, commercial active carbon, and commercial Fe2O3. Furthermore, the Fe-CN-3 catalyst can further trigger the reduction of other substituted PhNO2 with high activities. Importantly, the Fe-CN-3 catalyst is resistant to sulfur poisoning, exhibiting high durability, with no obvious decline of catalytic activity in five cycles. Systematic characterizations and density functional theory calculation (DFT) disclose that the isolated Fe atoms prefer to occupy four-coordinate doping configurations (Fe-N4) and the key to this mechanism is the hydrogen transfer process from PhNHOH* + HS* -> PhNH* + S + H2O.

Abstract ：
The utilization of H2S from industrial by-products as a hydrogen source offers an alternative approach for converting nitroarenes compounds (Ph-NO2) into aromatic amine (Ph-NH2) while also mitigating this environmental pollutant. However, the progress of this technology has been hindered by the lack of cost-effective and efficient catalysts. Herein, we present a porous K2MoSx/SiO2 catalyst synthesized using low-cost and environmentally friendly proline as template. The optimized K2MoSx/SiO2-proline catalyst achieves an 84 % conversion of Ph-NO2 with high Ph-NH2 selectivity for 91 % in the catalytic reduction of Ph-NO2 with H2S. Additionally, the K2MoSx/SiO2-proline shows considerable catalytic activity for the reduction of various substituted nitroarenes, demonstrating its versatility and broad applicability. The in situ DRIFTS and DFT calculations indicate that the reaction favors the formation of the essential intermediate *Ph-NO through a single H-induced pathway before proceeding to hydrogenation to yield Ph-NH2.

Abstract ：
Hydrogen sulfide (H2S), a secondary energy carrier with remarkable energy density, has emerged as an innovative hydrogen donor for the hydrogenation of nitroarenes. Nevertheless, the lack of efficient catalysts has impeded the development of this novel resource utilization method. Here, we proposed a facile and eco-friendly approach for the synthesis of isolated Cu sites on MXene catalysts by a combination of Lewis acid salt melt etching and oxidative dispersion. The as-designed MXene catalysts demonstrate high activity and product selectivity towards different nitroarenes at 70 degrees C within a 2 h reaction. The in-situ characterizations and DFT calculations reveal that the active Cu sites significantly lower the energy barriers for the nitro dissociation and hydrogenation of intermediates, facilitating amino formation. The mechanism involves an acceleration of the hydrogen transfer process over C6H5NO2*, leading to hydroxylation of the nitro group followed by deprotonation, ultimately resulting in the formation of an amino group.

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 ：
The reduction of nitrobenzene (Ph-NO2) to aniline (Ph-NH2) utilizes H2S as a hydrogen donor. This approach alleviates environmental pollution while enabling resource utilization. However, it remains a challenge to develop sulfur-resistant catalysts. Herein, we fabricated a series of MoS2/ZrO2 catalysts via crystalline phase modulation engineering for the reduction of Ph-NO2 by H2S to Ph-NH2. Systematic experiments demonstrate that amorphous ZrO2 has the highest concentration of oxygen vacancies (Ov), which exhibits the highest activity and stability. As a result, the MoS2/a-ZrO2 achieves a Ph-NO2 conversion of 92 % and a Ph-NH2 selectivity of 85.7 % at 1.5 MPa and 90 degrees C, which is superior to MoS2/m-ZrO2, MoS2/t-ZrO2, MoS2 and ZrO2. In situ FT-IR measurements combined with full two-dimensional time of flight chromatography suggest a double H-induced dissociation pathway for the reduction of Ph-NO2 to Ph-NH2 by H2S. This study offers a viable strategy for the valorization of H2S into valuable resources.

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 catalytic cleavage of carbon-sulfur (C & boxH;S) double bonds on the metal sites without deactivation has aroused great interest in both fundamental catalytic research and industrial chemistry. Herein, activity descriptors are developed via machine learning and density functional theory (DFT) calculations to screen transition-metal single-site catalysts, which quantify the effect of both atomic electronic properties and coordination configuration on the hydrolysis of C & boxH;S double bonds. The valence electron number and electronegativity of active sites are found to be well related to C & boxH;S activation and sulfur poisoning, where Fe demonstrates high catalytic potential among a series of metal centers. On the other hand, the isolated Fe-1 and Fe-2 sites favor carbonyl sulfide (COS) adsorption and activation, while the COS easily dissociates into *S and *CO on Fe-3 hollow site, thus resulting in the formation of robust Fe-S bonds and catalyst deactivation. As anticipated, the as-designed Fe-1-N-4 site achieves a COS conversion of ca. 96% at 100 degrees C, slightly better than the Fe-2-N-4 site, approximately 8 times higher than that of the Fe/C, which is also better than those of other monatomic catalysts (such as Co-NC, Ni-NC, Sn-NC, and Bi-NC). The combination of in situ characterizations and theoretical calculations suggests that *COS and *H2O/*OH have a competitive adsorption relationship on Fe-N-4 sites, and two Fe-N-4 sites can synergistically catalyze the COS hydrolysis through the spilled H and OH.

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 ：
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.
