Ammonia(NH_(3)), as an important chemical substance and clean energy carrier, plays an indispensable role in industrial and agricultural production. The electrocatalytic synthesis of NH+3 under mild conditions has attracted worldwide attention in the energy field due to its environmental friendliness and cost efficiency,but unsatisfactory NH_(3) yields and Faradaic efficiencies are restricting its development. The introduction of defect has been demonstrated as a feasible way to overcome the disadvantages of electrochemistry, as it can regulate the electronic structure and modulate coordination environment of electrocatalysts, which further create active sites and enhance nitrogen adsorption. In this regard, it is necessary to understand the effects of various types of defects on electrocatalysts based on the latest progress in the defect engineering for nitrogen reduction reaction(NRR). In this review, the concept, classifications, and characterization of defects as well as the approaches to create them in electrocatalysts are firstly ***, certain types of defects(vacancy, dopant, amorphism, edge/corner, and porousness) affecting the performances of various electrocatalysts are further described. Finally, the summary and challenges of electrocatalytic ammonia synthesis are proposed to design advanced electrocatalysts with high efficiency.

在模拟页岩气藏体系中研究了CH_(4)和CO_(2)在页岩主体矿物成分SiO_(2)孔隙中的吸附和扩散性能。结果表明:CH_(4)和CO_(2)之间存在着强烈的竞争吸附,高压低温能够促进两种组分气体的吸附,但不利于其扩散行为,同时CH_(4)比CO_(2)更容易扩散。孔壁对CH_(4)的吸附以非键相互作用为主,CO_(2)争夺吸附位点的行为可以有效抑制CH_(4)的吸附,而随着CO_(2)占比的增加,抑制效果更加显著。CO_(2)和CH_(4)在孔隙中的吸附行为均是典型的物理吸附,且CO_(2)具有更高的平均等量吸附热。

文章基于2011—2020年沪深两市A股上市公司的样本数据,研究高管与员工之间的薪酬差距对企业创新投入的影响路径,并且对比分析了企业环境因素及特有属性对两者关系的影响。实证结果显示:高管—员工薪酬差距与企业创新投入的关系存在阈值,呈“倒U”型关系;大部分高股权激励企业、市场竞争激烈企业以及高新技术企业的高管—员工薪酬差距没有超过阈值,可以通过扩大高管—员工薪酬差距来激励企业增加创新投入,而高融资约束的企业扩大高管—员工薪酬差距则会限制企业的创新投入;国有企业的高管—员工薪酬差距与企业创新投入不存在显著的关系。

中国天然气主要分布在鄂尔多斯盆地、四川盆地、塔里木盆地和柴达木盆地,以煤型气为主,含有部分油型气和少量生物气。中国主要油型盆地具有油多气少的特点,与鄂尔多斯等以产气为主的盆地相比,天然气探明储量和产量也远远不足。全球天然气以油型气为主,且大型油型盆地表现出油气资源俱丰的特征,这与中国天然气类型与勘探现状有明显差异。通过国内外油气勘探成果与认识的调研,在总结油型气勘探领域认识的基础上,对比国内外含油气盆地的成藏条件,对中国油型盆地油型气的生气潜力进行分析,认为中国油型盆地具有巨大的油型气勘探潜力,发展前景广阔,是中国未来天然气勘探的重要方向之一。
