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 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 ：
Cobalt spinel oxide (Co3O4) is a promising nonprecious catalyst for methane combustion, and improving its catalytic performance through structural modulation is desirable. Herein, layer-structured Cu2+-Co2+-Co3+ hydrotalcite-like compounds (HTlcs) were synthesized via methanol-assisted oxidative intercalation and used as a single-source precursor to prepare copper-cobalt spinels for the first time. Their characterizations reveal that single-phase and composition-tunable Cu2+-Co2+-Co3+ HTlcs are quantitatively formed. Upon calcination, Cu-Co HTlcs are decomposed into CuxCo3-xO4 spinels with a copper content of up to 10 at.%. X-ray photoelectron spectroscopy and X-ray absorption spectroscopy indicate that copper ions are incorporated into the Co3O4 lattice as tetrahedrally coordinated Cu+/Cu2+ and octahedrally coordinated Cu2+. The presence of abundant Cu+ suggests a redox cycle between Co3+/Co2+ and Cu2+/Cu+ couples, highlighting a strong electronic interaction between copper and cobalt species. The strong Cu-O-Co interaction not only increases oxygen vacancies and surface lattice oxygen mobility by weakening the Co-O coordination but also drastically enhances cobalt reducibility. Copper-cobalt spinels exhibit noticeably improved catalytic activity, and the highest activity is observed for Cu10-Co3O4, facilitating nearly complete CH4 conversion at 500 degrees C under a space velocity of 36,000 mL gcat - 1h- 1. This catalyst also manifests good cycle stability, long-term stability, and resistance to water vapor. The synergetic effect between Co3+/Co2+ and Cu2+/Cu+ redox couples plays a key role in improving catalytic activity. The proposed HTlc strategy may provide a new opportunity for the controlled preparation of various bimetallic and multimetallic cobaltite spinels for different applications.

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 ：
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 ：
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 ：
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 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 ：
The activation of H2O is a key step of the COS hydrolysis,which may be tuned by oxygen vacancy defects in the catalysts.Herein,we have introduced Cu into Co3O4 to regulate the oxygen vacancy defect content of the catalysts.In situ DRIFTS and XPS spectra reveal that COS and H2O are adsorbed and activated by oxygen vacancy.The 10 at％Cu doped Co3O4 sample(10Cu-Co3O4)exhibits the optimal activity,100％of COS conversion at 70 ℃.The improved oxygen vacancies of Cu-Co3O4 accelerate the activation of H2O to form active-OH.COS binds with hydroxyl to form the intermediate HSCO2,and then the activated-OH on the oxygen vacancy reacts with HSCO2 to form HCO3.Meanwhile,the catalyst exhibits high catalytic stability because copper species(Cu+/Cu2+)redox cycle mitigate the sulfation of Co3O4(Co2+/Co3+).Our work offers a promising approach for the rational design of cobalt-related catalysts in the highly efficient hydrolysis COS process.
