Graphdiyne(GDY),which is composed of sp2-/sp-hybridized carbon atoms,has attracted increasing attention.In the structure of GDY,the existence of large triangular-like pores,well dispersed electron-rich cavities as well as a large π-conjugated structure endows GDY with a natural bandgap,fast electron/ion transport,and tunable electronic properties.These unique features make GDY competitive in areas of gas separation and capture,electronics,detectors,catalysts,biomedicine and therapy,and energy-related fields.Benefiting from the facile synthesis method,various GDY structures and GDY-based composites have been successfully prepared and show great potential in the practical application of energy storage and catalysis areas.Here,this review aims at providing a timely and comprehensive update on the preparation and application of GDY materials.The current development of GDY materials in various electrochemical fields especially in energy conversion,energy storage,and catalysis is mainly summarized.Moreover,the potential development prospects are also discussed.

基于河源雷达站的历史观测数据,挑选不同灾害天气(台风、前汛期暴雨、大范围强对流)下对应的天气系统,采用VAP方法对这些天气系统的风场进行反演并分析,结果表明:该方法对于前汛期暴雨类型天气系统能够较好反演出整体风场分布及切变线的位置、移动趋势等;对于台风系统在台风一二象限反演效果较好,但反演出的风场只能指示回波的移动方向,对于台风内部风场结构反演效果则不佳;对强对流天气系统能够很好反演出环境风场以及指示系统的移动方向,但对于系统内部中小尺度系统反演方法效果不佳.
