Abstract
Expression of concern for ‘Synthesis of a Fe3O4@P4VP@metal–organic framework core–shell structure and studies of its aerobic oxidation reactivity’ by Zongcheng Miao et al., RSC Adv., 2017, 7, 2773–2779, https://doi.org/10.1039/C6RA25820D.
The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the integrity of the XRD data in Fig. 2c and d.
The Royal Society of Chemistry has asked the affiliated institution (Beijing University of Chemical Technology) to investigate this matter and confirm the integrity and reliability of the XRD data in Fig. 2c and d.
An expression of concern will continue to be associated with this manuscript until we receive information from the institution on this matter.
