The legend to Fig. 8 of this Article contains a typographical error. The first sentence of this legend should read ‘(a) Co and (b) Ru₃Co models.’

The Results section contains two typographical errors. The penultimate sentence of the first paragraph of the section ‘Electrochemical characterization for HER catalysis’ should read ‘It was also found that S-4 with lower Ru content (3.58 wt.% Ru in RuCo@NC catalyst, obtained from ICP) showed better activity than the etched counterpart with higher Ru content (17.7 wt.% Ru in RuCo alloy, obtained from ICP), which was in good agreement with the above-mentioned trend of overpotentials.’ In the same section, ‘Especially, the S-4 catalyst exhibited an ASA*C_S of 1.242 mA cm⁻²’ should read ‘Especially, the S-4 catalyst exhibited an ASA*C_S of 1.242*C_S mA cm⁻²’.

The legend to Supplementary Fig. 14 incorrectly states that the Δj values plotted in h) correspond to those at 0.15 V vs RHE. The Δj values in fact correspond to those at 0.1 V vs RHE.
