| 摘 要： | 析氢反应是电解水产制氢的关键反应之一.在碱性条件下,由于催化剂表面与反应过程中产生的氧物种、氢物种与催化剂的吸附未处于最佳状态,析氢反应动力学往往比较缓慢,比在酸性条件下慢2-3个数量级.目前,铂基纳米催化剂被认为是最优的析氢催化剂,但因价格昂贵、稳定性较差,限制了其在电解水器件上的大规模应用.因此,设计一种价格较为低...

| Abstract: | The development of high-performance electrocatalysts for hydrogen evolution reaction (HER) is of great significance for green, sustainable, and renewable energy conversion. Herein, we report the synthesis of amorphous Ru clusters on Co-doped defect-rich hollow carbon nanocage (a-Ru@Co-DHC) as an efficient electrocatalyst for HER in the basic media. Due to the advantages such as high surface area, rich edge defect, atomic Co doping and amorphous Ru clusters, the as-made a-Ru@Co-DHC displays an efficient HER performance with a near-zero onset overpotential, a low Tafel slope (62 mV dec-1), a low overpotential of 40 mV at 10 mA cm-2 and high stability, outperforming the commercial Ru nanocrystal/C, commercial Pt/C, and other reported Ru-based catalysts. This work provides a new insight into designing new metal doped carbon nanocages catalysts supported by amorphous nanoclusters for achieving the enhanced electrocatalysis. |
