Abstract
Expression of concern for ‘Cobalt metal–organic framework-based ZIF-67 for the trace determination of herbicide molinate by ion mobility spectrometry: investigation of different morphologies’ by Mehdi Davoodi et al., RSC Adv., 2021, 11, 2643–2655, DOI: https://doi.org/10.1039/D0RA09298C.
The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the reliability of the XRD data in Fig. 3a and the PL spectroscopy data in Fig. S2. An investigation is underway, and an expression of concern will continue to be associated with the article until a final outcome is reached.
