Abstract
Correction for ‘Reversible lattice oxygen participation in Ru1−xO2−x for superior acidic oxygen evolution reaction’ by Jia Cao et al., J. Mater. Chem. A, 2025, https://doi.org/10.1039/D5TA01484K.
The authors regret that in the original article some minor errors were present in Fig. 3 and 4 that were not corrected before publication. The specific details corrected are as follows:
(1) In Fig. 3(f), the x-axis unit should have read ‘A’ rather than ‘mA’.
(2) In Fig. 4(a), some species labels (e.g., O34) were incorrect and have been updated to 34O2.
(3) In Fig. 4(e), the x-axis label should have read ‘Wavenumber’ rather than ‘Wavelength’.
Updated versions of Fig. 3 and 4 are as displayed below, accompanied by the original captions which are unchanged.
