Retraction of: Scientific Reports, published online 02 November 2021 The Editors have retracted this article. After publication concerns were raised that the XRD spectra in Figure 8 are identical and that the data points in Figure 16 and Figure 18 are the same although they report the results of different experiments. The authors are unable to provide the original data for examination. In addition, an investigation by the Editors has shown inappropriate changes in authorship during the review process. The Editors no longer have confidence in the results and conclusions presented. Jawad Ahmad disagrees with this retraction. Fahid Aslam, Jesús de-Prado-Gil and Shaker M.A.Qaidi did not respond to the correspondence from the Editors about this retraction. The Editors were not able to obtain current contact details for Rebeca Martinez-Garcia and Ameni Brahmia.
