Abstract
Expression of concern 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 Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the characterization of g-C3N4, specifically in Fig. 1B, 3 and 5C, as the same sample was used to make composites in different papers and systems.
The authors have been alerted and are in the process of addressing this matter by means of repeating the characterization for consideration as a correction. An expression of concern will continue to be associated with the article until the authors provide their repeated characterization and it has been assessed for publication.
