Amorphous Ru nanoclusters onto Co-doped 1D carbon nanocages enables efficient hydrogen evolution catalysis

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