Electrochemical nitrogen reduction reaction(NRR)paves a new way to cost-efficient production of ammonia,but is still challenging in the sluggish kinetics caused by hydrogen evolution reaction competition and chemical inertness of N≡N ***,we report a“dual-site”strategy for boosting NRR performance.A high-performance catalyst is successfully constructed by anchoring isolated Fe and Mo atoms on hierarchical N doped carbon nanotubes through a facile self-sacrificing template route,which exhibits a remarkably improved NH3 yield rate of 26.8μg·h^(−1)·mg with 11.8%Faradaic efficiency,which is 2.5 and 1.6 times larger than those of Fe/NC and Mo/*** enhancement can be attributed to the unique hierarchical structure that profits from the contact of electrode and electrolyte,thus improving the mass and electron *** importantly,the in situ Fourier transform infrared spectroscopy(in situ FTIR)result firmly demonstrates the crucial role of the coupling of Fe and Mo atoms,which can efficiently boost the generation and transmission of*N2Hy intermediates,leading to an accelerated reaction rate.

面对错综复杂和快速变化的商业环境,组织要想做出快速响应,领导者的有效倾听显得非常重要。通过文献综述发现,现有研究尚未对领导倾听的概念形成统一界定,且理论视角和研究层次较为单一,这不利于我们深入理解领导倾听的内涵及其多层次效应。事实上,作为一种领导行为,领导倾听不仅会对领导者自身产生影响,而且会给团队及其下属带来影响。因此,本研究基于二元互动情境,从沟通信息和支持员工两方面对领导倾听的内涵进行探索性研究,并从领导力效能的评价对象(领导者、团队、员工)出发,结合多层次、多理论、多研究方法的全景研究范式逐步揭示领导倾听对不同对象的不同效应、黑箱机制及边界条件。本研究不仅开拓了倾听研究的新思路和新视角,而且为企业增强领导倾听的积极效能提供了管理启示。

石墨烯因其出色的比表面积和单层结构而被广泛认为是一种理想的电极材料.然而,实验制备的石墨烯常因官能团、缺陷和位错的引入而出现褶皱和变形.针对这一问题,本文构建了一系列具有不同幅度褶皱(a=0~6.6?)的石墨烯片,并运用分子动力学模拟来研究这些褶皱石墨烯表面的双电层结构.本研究旨在探讨不同褶皱高度和充电状态下双电层的变化规律,及其与超级电容器储能性能之间的关系.研究发现,褶皱石墨烯模型内部的离子浓度随电压的增加呈现多峰层状分布,而表面离子浓度与施加的电压正相关.此外,石墨烯的褶皱结构能够减少离子和水对电极电压响应的敏感性.在不同电压条件下,褶皱型石墨烯结构的面积比电容(C_A)始终高于其平面对应区域,突出了其在提升双电层储能性能上的优势.本研究揭示了石墨烯褶皱结构在调节离子分布、降低电压敏感性,以及增强电化学储能性能方面的特有作用机制.
