Abstract
Expression of Concern for ‘Palladium supported on mixed-metal–organic framework (Co–Mn-MOF-74) for efficient catalytic oxidation of CO’ by Reda S. Salama et al., RSC Adv., 2021, 11, 4318–4326, https://doi.org/10.1039/D0RA09970H.
The Royal Society of Chemistry is publishing this Expression of Concern in order to alert readers that concerns have been raised regarding the XRD data in Fig. 1 and 2. An independent expert has examined the raw data and found the amount of smoothing applied has made the data unreliable.
The authors have been alerted and are in the process of addressing this matter by means of repeating the measurements with better signal-to-noise ratio for consideration as a correction. An Expression of Concern will continue to be associated with the article until the authors provide their repeated characterisation and it has been assessed for publication.
