“…The results are presented in Table 1 [15]. Studies have indicated that eutrophication is evident when phosphorus and nitrogen concentrations exceed 0.02 mg/L [16]. This suggests that the Xi River is in a eutrophic state.…”

This study focused on assessing the impact of pollutants discharged from the Fuxin Meng Wastewater Treatment Plant (FMWWTP) on the microbial communities in the Xi River; specific comparison between upstream and downstream regions was made. Water samples were obtained by mixing morning, midday, and evening sampling at two points: one upstream and one downstream, each 500 m from the FMWWTP outfall. Utilizing metagenomic sequencing in conjunction with measured conventional physical and chemical properties, the research aimed to elucidate differences in microbial community structure, metabolic functions, potential biological contamination, and antibiotic resistance gene prevalence. The findings indicated a notable decrease in microbial diversity downstream compared to upstream; this was influenced primarily by the effluent from FMWWTP. This disparity in microbial diversity was evident at various taxonomic levels, with downstream samples showing higher diversity at the phylum level than at the genus level. Furthermore, downstream microbial populations demonstrated a broader range of metabolic and functional genetic diversity. Interestingly, the abundance of metabolic systems was generally greater downstream, with the notable exception of energy metabolism. This could be attributed to the stress imposed on downstream microorganisms by organic chemicals discharged from the treatment plant, and this prompts an enhanced metabolic decomposition function. The study also uncovered significant levels of potential biological contamination and antibiotic resistance gene pollution. This was more pronounced downstream of FMWWTP. In conclusion, discharge from FMWWTP has a substantial impact on the microbial communities of the Xi River, and this underscores the urgent need to optimize wastewater treatment processes to better comply with environmental quality standards.

“…The excellent stability of Cu‐doped ZIF‐8‐derived carbon material can be attributed to several factors. Firstly, doping the Cu element promotes the formation of stable carbon structures and regulates the graphitization degree, thereby enhancing chemical stability, [55] especially at elevated temperatures. Secondly, the nitrogen element in ZIF‐8 material can form amine and amino groups with carbon atoms, increasing the surface redox activity of the carbon material and thereby enhancing stability [56] .…”

Electrochemical reduction of carbon dioxide presents a promising pathway to tackle global energy and environmental challenges. Porous carbon materials from metal‐organic frameworks exhibit high specific surface area, abundant active sites, and adjustable pore structure, demonstrating excellent electrocatalytic performance. With their abundant resources and tunability, copper‐based catalysts are well‐suited for efficient carbon dioxide conversion. However, the selectivity and stability of copper‐based catalysts is poor. This study presents the preparation of the first Cu‐doped ZIF‐8‐derived carbon materials and investigates their effect on electrocatalytic carbon dioxide reduction. At the optimal potential of −0.7 V vs. RHE, the CO Faradaic Efficiency (FE) of the Cu0.5‐N−C catalyst reaches 89 %. Furthermore, the electrochemical current density and CO FE of Cu0.5‐N−C catalyst remain nearly unchanged within 13 hours in 0.1 mol L−1 KHCO3 electrolyte. Compared to most of the reported copper‐based catalysts, Cu0.5‐N−C exhibits better stability. Characterization results show that Cu0.5‐N−C has a larger Cu‐N4, higher pyridinic N content, larger specific surface area, and average pore size, which help promote CO2 adsorption and enhance catalyst stability. This work provides new insights and pathways for electrocatalytic carbon dioxide reduction, with enormous potential to contribute to the global energy transition and environmental protection.
