In the article by Huang et al., ‘TT-Nb_2_O_5_ with dual-band modulation and exceptional performance retention for fast-responsive electrochromics’ (National Science Review, Volume 12, Issue 6, 2025, nwaf154, https://doi.org/10.1093/nsr/nwaf154), the erroneous notation ‘Nb 3d’ was used at page 1, line 23; page 2, line 39; page 4, lines 1 and 5; page 5, line 3, as well as page 9, lines 17 and 22.
Based on the electron configuration of Nb (4d^4^5s^1^), the valence d-orbital of Nb corresponds to the 4d orbital instead of the 3d orbital. All the aforementioned instances of ‘Nb 3d’ shall be revised to ‘Nb 4d’.
This constitutes a conceptual notation error only, with no impact on the experimental data, core conclusions, or the logical framework underpinning the material’s mechanism.
