Expression of concern: Self-assembled membrane manufactured by metal–organic framework (UiO-66) coated γ-Al2O3 for cleaning oily seawater

Expression of concern for ‘Self-assembled membrane manufactured by metal–organic framework (UiO-66) coated γ-Al₂O₃ for cleaning oily seawater’ by Cunlong Li et al., RSC Adv., 2019, 9, 10702–10714, DOI: 10.1039/C9RA00521H.

The following article ‘Self-assembled membrane manufactured by metal–organic framework (UiO-66) coated γ-Al₂O₃ for cleaning oily seawater’ has been published in RSC Advances.The XRD data shown in Fig. 6b is the same for the UA composites (shown in green) and UiO-66 particles (shown in red), with the exception of two peaks that are not present in the UiO-66 pattern.In Fig. 7a, the panel for 0.03 MPa is a rotated and processed duplicate of the panel for 0.02 MPa.The authors were contacted for comment and asked to provide raw data but have not responded to these concerns. RSC Advances is publishing this Expression of Concern to alert readers to the concerns raised. An Expression of Concern will continue to be associated with the article until we receive conclusive evidence regarding the reliability of the reported data.Laura Fisher11^th February 2022Executive Editor, RSC Advances
