摘要

随着水电解催化剂的重要性日益显现，开发高效、廉价的水电解电催化剂在可再生氢能技术中发挥着至关重要的作用。在本研究中，使用电子束蒸发器和在炉中热分解气态CH4，成功地制备了用于析氢反应（HER）的1nm厚度的TiC负载Ru催化剂。所制备的Ru/TiC催化剂在10mAcm-2下的过电位为55mV，在碱性析氢反应中表现出优异的性能。此外，我们证明了Ru/TiC优异的HER性能归因于载体的高表面积和金属-载体的相互作用。

Highly Active Electrocatalyst based on Ultra-low Loading of Ruthenium Supported on Titanium Carbide for Alkaline Hydrogen Evolution Reaction

With the emerging importance of catalysts for water electrolysis, developing efficient and inexpensive electrocatalysts for water electrolysis plays a vital role in renewable hydrogen energy technology. In this study, a 1nm thickness of TiC-sup-ported Ru catalyst for hydrogen evolution reaction (HER) has been successfully fabricated using an electron (E)-beam evaporator and thermal decomposition of gaseous CH 4 in a furnace. The prepared Ru/TiC catalyst exhibited an outstanding performance for alkaline hydrogen evolution reaction with an overpotential of 55 mV at 10 mA cm -2 . Furthermore, we demonstrated that the outstanding HER performance of Ru/TiC was attributed to the high surface area of the support and the metal-support interaction.
