Abstract
Correction for ‘Enhanced photocatalytic activity of g-C3N4/MnO composites for hydrogen evolution under visible light’ by Na Mao, et al., Dalton Trans., 2019, 48, 14864–14872, https://doi.org/10.1039/c9dt02748c.
The authors regret that incorrect data for the characterization of g-C3N4 was presented in this article since the same sample of g-C3N4 was used as the control sample to make composites in different papers and systems. All updated data re-measured from the original g-C3N4 sample are shown here (relevant parts of Fig. 1–5). Table S3 has been updated in the SI file, with the corrected version also shown here as Table 1.

Additionally, the following discussions should be revised according to the updated data.
1. On page 14869, line 2 (right column), the discussion “which is almost ten times that of g-C3N4 (204 μmol h−1 g−1)” should be corrected to “which is almost ten times that of g-C3N4 (200 μmol h−1 g−1)”.
2. On page 14869, line 34 (right column), the discussion “The time-resolved fluorescence decay spectrum also demonstrated that the g-C3N4/MnO-5 composite has a shorter excited-state lifetime of 10.79 ns than the bulky g-C3N4 (17.62 ns)” should be corrected to “The time-resolved fluorescence decay spectrum also demonstrated that the g-C3N4/MnO-5 composite has a shorter excited-state lifetime of 10.79 ns than the bulky g-C3N4 (12.19 ns)”.
The conclusion made in the paper remains valid and the related discussions are not affected by this change.
An independent expert has viewed the corrected images and has concluded that they are consistent with the discussions and conclusions presented.
This correction supersedes the information provided in the Expression of Concern related to this article.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
