Evidence Details
The mixture was transferred into a Teflon-lined microwave autoclave (100 mL) and treated with microwave irradiation in a microwave reactor (XH-8000, XiangHu Science and Technology Development Co., Ltd.) at 150 °C for 30 min.
The optimal electrocatalyst (Ru@GNs300) was achieved by annealing at 300 °C, giving an overpotential of 40 mV at a current density of 10 mA cm−2 together with superior durability in the HER performance test in 1 M KOH.
At a constant overpotential of 40 mV, Ru@GNs300 showed an excellent HER stability with the current density decreased in magnitude only slightly over 24 h of continuous operation.
Additional source evidence: source values include 20 °C, 1000 °C.
Particle-size evidence: source values include 2 nm.
