化石燃料的过度使用导致了严重的环境问题,因此,迫切需要人们对能源生产和储存方式进行变革.电催化在清洁能源转换中发挥着重要的作用,是推动可持续能源生产技术不断发展的重要驱动力.单原子催化剂(SACs)因具有独特的物理和化学性质而表现较高的电催化活性,因而成为研究热点.通过调控金属单原子的配位环境,可以有效调节SACs的几何和电子结构,进而优化电催化效率.金属有机骨架(MOFs)具有孔结构丰富、表面积大和配体可调节等结构特性,因此在制备SACs方面表现出巨大潜力.本文旨在总结以MOFs为前驱体制备SACs的最新进展,深入探讨单原子空间分布、配位结构和电子结构等局部配位环境对电催化活性的影响.此外,对密度泛函理论在研究SACs电催化反应中的应用进行了讨论和分析.本文系统地介绍了以MOFs为前驱体制备SACs的合成策略、表征方法、电催化应用和反应机理的研究进展,并对其未来的发展进行了展望.首先,概述了以MOFs为原料制备SACs的多种策略,分析了各自的优缺点及改进方向.然后,介绍了SACs的结构表征及电催化反应机理的原位表征技术,剖析了现有技术面临的挑战.再后,重点介绍了一些经典的制备SACs案例,对以MOFs为源制备的SACs在电催化析氢反应、析氧反应、氧还原反应、CO_(2.还原反应及氮还原消除等的应用进行了系统总结,并简要回顾了其在光催化、热催化、酶催化方向的应用.最后,探讨了SACs面临的挑战及解决方案:(1)目前采用的以MOFs为源制备SACs方法存在能耗高、污染环境等问题,应开发出环保可持续的合成方法以降低生产成本,并将其对环境的影响降到最低.(2.应利用原子水平控制技术制备双原子或三原子多功能电催化剂,并根据SACs的应用场景调整其配位结构,以优化性能.(3)需研发更先进的测试仪器,解决测试结果区域化、效率低、测试与实际结果存在偏差以及测试成本较高等问题.(4)基于SACs的结构特性,结合先进的测试仪器与理论计算,深入探究反应机理,为新一代电催化剂的设计提供指导.(5)随着信息技术的多维、多样和复杂化发展,可以借助机器学习,设计和开发新型SACs,推动电催化领域的持续创新.综上,本文系统地介绍了以MOFs为材料制备SACs的优势、设计原理、表征手段,并对SACs在电催化应用方面的研究进展与面临的挑战进行了总结,希望能为SACs相关方面的研究提供有价值的参考和借鉴.

获取土壤重金属的含量特征及空间分布是预防土壤污染和制定环保政策的关键.选取济南市长清区为研究区,系统采集304处表层土壤样品(0~2. cm),利用多源遥感数据构建土壤重金属的光谱特征、时间特征和空间特征;进一步采用相关分析法选择出与土壤重金属密切相关的时-空-谱特征,并将其作为输入自变量,实测土壤砷(As)含量值为因变量,建立基于随机森林(RF)算法的空间预测模型,完成土壤重金属的含量估算和空间分布预测.结果表明:(1)As含量均值超出背景值43.17%,低于农用地土壤污染风险规定的筛选值和管控值,表明As在土壤中出现富集,但处于可管控范围内.(2.在单个遥感特征构建的土壤重金属空间预测模型中,精度由高到低依次为:空间特征(RPIQ=3.87)>时间特征(RPIQ=2.57)>光谱特征(RPIQ=2.50),空间特征对土壤重金属空间预测最为重要.(3)基于“时间-空间”、“时间-光谱”和“空间-光谱”组合特征的土壤重金属空间预测模型均优于单个特征构建的模型,其精度系数RPIQ值分别为4.81、 4.2.和4.70.(4)利用“时间-空间-光谱”特征组合输入的随机森林模型达到最佳的空间预测精度(R^(2.=0.90;RMSE=0.77;RPIQ=5.68).(5)As在空间分布上从西北到东南含量逐步降低,主要受到黄河冲淤积和工业活动影响.研究采用的遥感时-空-谱特征结合随机森林算法的土壤重金属空间预测技术,可为土壤污染防治及环境风险管控提供有效的方法支持.

随着《大气污染防治行动计划》和《打赢蓝天保卫战三年行动计划》的相继实施,在高强度的污染治理下,中东部地区PM_(2.5)污染改善效果显著。为探讨在PM_(2.5)浓度不断降低的背景下,仍时有发生的武汉冬季重污染过程的成因及特征,以2.2.年12.武汉地区一次长达10 d的重污染过程为例,利用多种观测数据和嵌套网格空气质量预报模式系统(NAQPMS)分析污染过程中PM_(2.5)的化学组分特征和区域贡献等。结果表明:污染日二次无机盐SNA(SO_(4)^(2.)、NO_(3)^(-)和NH+4)和碳质组分(EC和OC)在PM_(2.5)中的占比高(分别为78%和18%),NO_(3)^(-)的占比从清洁日的36%上升到污染日的46%,是污染过程中占比最高的化学组分。污染期间,NO_(3)^(-)和SO_(4)^(2.)的浓度比为2.9~6.1,因此二次无机盐的主要来源可能是移动源;OC和EC的浓度比为3.0~9.8,因此碳质组分的主要来源可能是燃煤源。污染期间主要有河南-孝感-武汉和安徽-黄冈-武汉2.污染传输带,污染物传输以武汉周边城市的近距离输送为主,随着污染程度加重,武汉本地及武汉城市圈的区域贡献增加。重度污染天是静稳天气下持续的偏弱东风和西北风输送的污染气团在不易扩散的天气条件下累积形成的。

In 1999, Diexi paleo-dammed lake(2.49 m a.s.l.) was discovered around Diexi town along the Minjiang River in Sichuan province. Diexi is located where the eastern edge of the Tibetan Plateau and the Sichuan Basin meet. The dammed lake was formed during the Last Glacial Maximum of the Late Pleistocene(~30,000 years ago) and began to empty about 15,000 years ago. The lacustrine sediments(up to 2.0 m thick) preserve abundant paleoenvironment information. In this paper, a mass of oxygen isotopes and 14 C dating from drilled cores are analyzed and discussed. The δ18 O curve on the paleo climate from this section is comparable with the coeval paleo climatic curves of ice cores and karsts in china and others. Furthermore, the physical model testing has confirmed that the disturbed zones in the core are caused by strong earthquakes occurred at least 10 times, which implies strong crustal deformation, as an important driving force, affecting climate change. This study provides a new window to observe East Asian monsoon formation, paleoenvironmental evolution and the global climate change.
