Abstract

Correction for ‘High-efficiency methanol oxidation electrocatalysts realized by ultrathin PtRuM–O (M = Ni, Fe, Co) nanosheets’ by Yue Pan et al., Chem. Commun., 2020, 56, 9028–9031, DOI: 10.1039/D0CC00361A.

The authors regret that some of the data in the original article were incorrect. The corrected values are shown in Table 1 below.

Table 1

Incorrect data in original article	Correct data
Page 9029, left column: the specific activity of the Pt₇RuNi₂–O NS catalyst was stated as 9.82 mA cm⁻²	The specific activity of the Pt₇RuNi₂–O NS catalyst is 4.65 mA cm⁻²
Page 9029, right column: the specific activity of the Pt₇RuNi₂–O NS catalyst was stated as 9.82 mA cm⁻², 12.9 times higher than that of the commercial Pt/C catalyst (0.76 mA cm⁻²)	The specific activity of the Pt₇RuNi₂–O NS catalyst is 4.65 mA cm⁻², 6.12 times higher than that of the commercial Pt/C catalyst (0.76 mA cm⁻²)
Page 9030, left column: the specific activity of the Pt₇Ru₂Ni–O NS, Pt₇Ru_0.5Ni_2.5–O NS and Pt₇Ru₃–O NS catalysts was stated as 9.68 mA cm⁻², 7.15 mA cm⁻² and 2.83 mA cm⁻², respectively	The specific activity of the Pt₇Ru₂Ni–O NS, Pt₇Ru_0.5Ni_2.5–O NS and Pt₇Ru₃–O NS catalysts is 3.93 mA cm⁻², 3.31 mA cm⁻² and 1.46 mA cm⁻², respectively
Page 9030, right column: the specific activity of Pt₇RuCo₂–O and Pt₇RuFe₂–O was stated as 7.83 mA cm⁻² and 6.31 mA cm⁻², respectively	The specific activity of Pt₇RuCo₂–O and Pt₇RuFe₂–O is 4.35 mA cm⁻² and 2.25 mA cm⁻², respectively

Fig. 2 and 4 also included some incorrect data and corrected versions of these figures are presented here. The graphical abstract included some incorrect data and this has been updated online with a corrected image. These errors do not affect the main results or conclusions of the paper.
