Abstract ：
Regulation of hydrogenation capacity in cobalt-based catalysts is crucial for the effective conversion of CO2 into methanol. Herein, we developed a cobalt catalyst supported on nitrogen-doped carbon (viz., Co-N/C), specifically enriched with pyridinic N bonding to the cobalt sites. The hydrogenation capacity of the Co-N/C catalyst was carefully tuned by controlling the arrangement of pyridinic and pyrrolic N dopants through the ammonolysis treatment of the ZIF-67 precursor. The incorporation of pyridinic N significantly reduces electron localization around the cobalt centers, thereby minimizing unwanted hydrogenation to methane. The optimized Co-N/C catalyst, characterized by a predominance of pyridinic N, achieved a turnover frequency of 47.8 h- 1 for methanol production under 2 MPa pressure and 180 degrees C in a slurry reactor, surpassing the performance of a conventional Co/C catalyst featuring pyrrolic N by a factor of seven. Additionally, the Co-N/C catalyst exhibited excellent long-term stability, generating 70 mmol of CH3OH and only 1.5 mmol of CH4 over five cycles (totaling 30 h). Both theoretical and experimental investigations revealed that pyridinic N has a greater affinity for bonding with Co compared to pyrrolic and graphitic N, and the pyridinic-N-cobalt serves as active sites for CO2 hydrogenation.

Abstract ：
Mangrove wetland ecosystem plays a vital ecological service function in carbon neutralization and coastal protection. In recent decades, a series of artificial mangrove wetlands have been produced. However, the sustainability of these kind of mangrove wetlands has not been fully studied, especially on the landscape scale. This study explored a set of robust and transplantable technical routines for assessing the sustainability of mangrove forest landscape. With the support of the Google Earth Engine (GEE) cloud platform, the temporal and spatial evolution pattern of artificial mangroves in the Luoyangjiang River estuary was obtained from 1990 to 2023. The landscape index is calculated by Fragstats and screened by the Spearman rank correlation coefficient, and 9 key indicators are obtained. The Landscape Sustainability Development Index (LSDI) was calculated using landscape metrics and principal component analysis (PCA) to assess the sustainability of mangrove ecosystems. The LSDI derived from PCA scores, provides insights into the effectiveness of mangrove conservation and restoration efforts. From 1990 to 2023, the sustainability capacity of the Luoyangjiang wetland, as indicated by LSDI, has gradually increased. This trend suggests a positive trajectory towards enhanced ecological stability and resilience in the region. These findings contribute to the strategic objectives of carbon peaking and carbon neutrality in China, offering both theoretical insights and practical recommendations for ecological engineering.

Abstract ：
Sulphate-reducing microorganisms, or SRMs, are crucial to organic decomposition, the sulphur cycle, and the formation of pyrite. Despite their low energy-yielding metabolism and intense competition with other microorganisms, their ability to thrive in natural habitats often lacking sufficient substrates remains an enigma. This study delves into how Desulfovibrio desulfuricans G20, a representative SRM, utilizes photoelectrons from extracellular sphalerite (ZnS), a semiconducting mineral that often coexists with SRMs, for its metabolism and energy production. Batch experiments with sphalerite reveal that the initial rate and extent of sulphate reduction by G20 increased by 3.6 and 3.2 times respectively under light conditions compared to darkness, when lactate was not added. Analyses of microbial photoelectrochemical, transcriptomic, and metabolomic data suggest that in the absence of lactate, G20 extracts photoelectrons from extracellular sphalerite through cytochromes, nanowires, and electron shuttles. Genes encoding movement and biofilm formation are upregulated, suggesting that G20 might sense redox potential gradients and migrate towards sphalerite to acquire photoelectrons. This process enhances the intracellular electron transfer activity, sulphur metabolism, and ATP production of G20, which becomes dominant under conditions of carbon starvation and extends cell viability in such environments. This mechanism could be a vital strategy for SRMs to survive in energy-limited environments and contribute to sulphur cycling. This study uncovers a unique mechanism where a non-phototrophic sulphate-reducing microorganism adapts to environments with limited or depleted substrates. It does this by harnessing photoelectrons from semiconducting minerals that coexist extracellularly, which are then used for energy production and metabolism. image

Abstract ：
The disposal of discarded vulcanized natural rubber waste has presented substantial environmental challenges. This study aimed to investigate the degradation of vulcanized natural rubber through the utilization of enriched bacterial consortia with NRE3 derived from the soil. The highest weight loss of 38.84 % was achieved with NRE3 after four weeks of incubation. Additionally, the crosslinking density of rubber decreased by 32.3 % and the tensile strength decreased from 69.1 to 9.5 MPa. SEM analysis revealed the presence of significant cracks and holes on the surface of vulcanized natural rubber. Moreover, FT-IR and XPS analyses demonstrated a decrease in the sulfur (S) and carbon (C) content of the rubber, while the oxygen (O) content increased. The concentration of SO42- in the medium increased from 478.37 to 840.26 mg/L, indicating the collapse of the rubber structure. The NMR and GC-MS findings indicated the presence of degradation products, specifically polyisoprene oligomers and terpenoids. Through high-throughput sequencing analyses, Acinetobacter, Chryseobacterium, Stenotrophomonas and other bacterial were discovered in NRE3. Based on the chemical structure characterizations and molecular analyses, a degradation pathway was proposed. These findings pave a way for utilizing rubberdegrading microorganisms present in soil and contribute to the establishment of a biodegradation method for disposing of vulcanized rubber waste.

Abstract ：
Copper-based small-pore zeolites catalysts are the promising candidate catalysts for NOx abatement in current diesel vehicles with Chinese VI standards, due to the excellent NH3-SCR catalytic performance, hydrothermal stability, nitrogen selectivity and wide temperature window. However, the catalytic activity of copper-based small-pore zeolites is still significantly affected by sulfur oxides emitted from diesel vehicles, and even the irreversible deactivation occurs. The SO2-poisoning of Cu-based small-zeolites is mainly due to the accumulation of surface ammonium sulfate and sulfation of Cu active site sites. In this review, the research status of the structure and active sites of copper-based small-pore zeolites catalysts is summarized, and the sulfur poisoning mechanism of copper-based small-pore zeolites catalysts is discussed. Moreover, the research advance in the improvement of sulfur resistance of catalysts and the regeneration of sulfur-poisoned catalysts is also illustrated. The systematic understanding of mechanism of sulfur poisoning and regeneration is important for the design of novel, efficient catalyst. It is pointed out that the study on sulfur poisoning mechanism and regeneration mechanism of copper-based small-pore zeolites catalysts, as well as the synergistic effect of various poisoning factors and corresponding deactivation mechanism, are the main research directions for copper-based zeolites to be practically applied to ultra-low emission of nitrogen oxides in diesel vehicle exhaust in the future.
