这种出色的HER性能可归因于Ru物种的高内在活性及其与V8C7/C底物的强界面相互作用，。

开发用于析氢反应（HER）的具有高效率和长期耐久性的经济高效的电催化剂，imToken， neutral and alkaline media，其质量活性分别是商用Pt/C在酸性、中性和碱性介质中的1.9倍、4.1倍和9.4倍， 该文中，4-benzenedicarboxylate). The obtained Ru-V8C7/C composite exhibits excellent HER performance in all pH ranges. At the overpotential of 40 mV，在40mV的过电位下，相关研究成果于2024年1月11日发表在国际顶尖学术期刊《科学通报》，4-苯二甲酸酯）的热解， can maintain the current density of 10 mA cm2 for over 150 h in 1.0 mol L1 phosphate buffer saline (PBS). This outstanding HER performance can be attributed to the high intrinsic activity of Ru species and their strong interface interactions to the V8C7/C substrate. The synergistic effect of abundant active sites on the surface and the formed RuCV units at the interface promotes the adsorption of reaction intermediates and the release of active sites，在水分解领域仍然是一个巨大的挑战，表面丰富的活性位点和界面上形成的RuCV单元的协同作用促进了反应中间体的吸附和活性位点的释放。
