协同治理是中国应对气候变化和空气污染防治双重挑战的关键措施。但是，目前仍然没有一个合适的指标用于全面评估协同效应，现有的研究缺乏一个一致的框架用于比较相关研究结果。为此，本研究对协同指标进行了定义，指标意义为单位GDP的污染物产生量变化所带来的减排效应。通过耦合迪氏指数分解分析方法（LMDI）、排放-浓度响应曲面模型（RSM）和全球暴露反应关系模型（GEMM）构建综合分析框架，用来评估中国碳减排对大气污染物减排和公众健康的协同效应。研究结果表明，协同效应对SO2、NOx和PM2.5（空气动力学直径不大于2.5μm的主要颗粒物）的减排作用越来越重要。具体而言，协同控制对SO2、NOx和PM2.5的减排量从“十一五”时期（2006—2010年）的3.1 Mt、1.4 Mt和0.3 Mt增加到“十二五”时期（2011—2015年）的5.6 Mt、3.7Mt和1.9 Mt。与无控情景相比，协同效应使得PM2.5年均浓度降低了15%，从而在2015年避免了29万例（95%置信区间：0.28～0.30）由PM2.5引起的超额死亡。协同控制对于空气质量改善和公众健康保护的效应在人口密集的东部发达省市更加显著。未来随着城市化和碳中和进程的推进，协同效应有望继续增强。发达地区提前实现气候目标将同时为空气质量和公众健康带来更大的协同效益。

The performance of Ce-OMS-2 catalysts was improved by tuning the fill percentage in the hydrothermal synthesis process to increase the oxygen vacancy *** Ce-OMS-2 samples were prepared with different fill percentages by means of a hydrothermal approach(i.e.80%,70%,50%and 30%).Ce-OMS-2 with 80%fill percentage(Ce-OMS-2-80%)showed ozone conversion of 97%,and a lifetime experiment carried out for more than20 days showed that the activity of the catalyst still remained satisfactorily high(91%).For Ce-OMS-2-80%,Mn ions in the framework as well as K ions in the tunnel sites were replaced by Ce^4+,while for the others only Mn ions were replaced.O2-TPD and H2-TPR measurements proved that the Ce-OMS-2-80%catalyst possessed the greatest number of mobile surface oxygen *** and XAFS showed that increasing the fill percentage can reduce the AOS of Mn and augment the amount of oxygen *** active sites,which accelerate the elimination of O3,can be enriched by increasing the oxygen *** findings indicate that increasing ozone removal can be achieved by tuning the fill percentage in the hydrothermal synthesis process.

China’s dependence on coal for energy is prominent, leading to considerable uranium emissions that have invoked widespread concern due to their significant risks to both human health and the natural environment. Nonetheless, given the importance of uranium as a resource for nuclear fuel, there is substantial potential in harvesting uranium from the by-products of coal combustion to bolster nuclear power supplies. This investigation focuses on uranium-rich Lincang coal (LC coal) alongside conventional Shengli coal (SL coal) as subjects of study. A combination of experimental research and simulation calculations have been employed to intricately examine the presence of uranium in both coal and coal ash, as well as its dynamic migration and alterations throughout the combustion process. It is primarily found that uranium in uranium-rich coal predominantly associates with organic material, in contrast, uranium in conventional coal largely links with clay minerals. Upon burning, uranium forms uranates with alkaline earth metals, becomes concentrated in the coal ash, and exhibits a preference for accumulation in fine particles, revealing that the uranium content in PM1 could be up to 3-10 times that of PM10+ (particle size >10 μm). Uranium also has a tendency to enrich on the surfaces of aluminoxsilicate, iron oxide, and calcium oxide as fine particles undergo polymerization. The insights from this study are critically important for the strategic control and resourceful exploitation of uranium. © 2024, The Authors. All rights reserved.

Replacing fossil energy with renewable resources is an important means of reducing carbon emissions. As a by-product of fermentation to produce ethanol, fusel oil is a renewable organic liquid with a wide range of sources, and its use to partially replace diesel has high environmental benefits. The main component of fusel oil has strong water absorption, so this paper studies the stability and combustion performance of diesel blended with fusel oil after absorbing a small amount of water in the air. The characteristics of fusel alcohols were studied by analyzing the water-holding capacity of the main components in the fusel alcohols mixed with diesel. Three kinds of fuels (containing 20% fusel, no water;containing 20% fusel, and 6% water in the fusel;diesel) were selected for combustion experiments and analyzed the exhaust gas composition. The results demonstrate that the absorption of moisture from the air has no visible effect on the stability of the fuel and the fuel continues to remain single phase. Adding 20% fusel oil with water will increase break thermal efficiency by about 0.7%. The soot emission can be reduced by up to 47.5% and the NOx emitted by the water-containing fuel can be reduced by about 6.4%. At the same time, due to the significantly lower cost of fusel alcohol, under the same energy output from the engine, adding 20% fusel oil will reduce the cost by ~15%. Taken together, the incorporation of fusel oil into diesel at a ratio of 20% will not adversely affect the fuel, and it can be directly used in existing diesel engines. © 2022, The Authors.

Despite the extensive application of advanced oxidation processes（AOPs） in water treatment, the efficiency of AOPs in eliminating various emerging contaminants such as halogenated antibiotics is constrained by a number of factors. Halogen moieties exhibit strong resistance to oxidative radicals,affecting the dehalogenation and detoxification efficiencies. To address these limitations of AOPs,advanced reduction processes（ARPs） have been proposed. Herein, a novel nucleophilic reductant-namely, the carbon dioxide radical anion(CO2·-)-is introduced for the simultaneous degradation, dehalogenation, and detoxification of florfenicol（FF）, a typical halogenated antibiotic. The results demonstrate that FF is completely eliminated by CO2·-, with approximately 100% of Cl-and 46% of F-released after 120min of treatment. Simultaneous detoxification is observed, which exhibits a linear response to the release of free inorganic halogen ions（R2= 0.97, p < 0.01）. The formation of halogen-free products is the primary reason for the superior detoxification performance of this method, in comparison with conventional hydroxyl-radical-based AOPs. Products identification and density functional theory（DFT） calculations reveal the underlying dehalogenation mechanism, in which the chlorine moiety of FF is more susceptible than other moieties to nucleophilic attack by CO2·-. Moreover, CO2·--based ARPs exhibit superior dehalogenation efficiencies（> 75%） in degrading a series of halogenated antibiotics, including chloramphenicol（CAP）, thiamphenicol（THA）, diclofenac（DLF）, triclosan（TCS）, and ciprofloxacin（CIP）. The system shows high tolerance to the p H of the solution and the presence of natural water constituents, and demonstrates an excellent degradation performance in actual groundwater, indicating the strong application potential of CO2·--based ARPs in real life. Overall, this study elucidates the feasibility of CO2·-for the simultaneous degradation, dehalogenation, and detoxification of ha
