Retraction notice to “Passivation layer–dependent catalysis of zinc oxide nanostructures” [Mater. Today Chem. 22 (2021) 100592] (Materials Today Chemistry (2021) 22, (S2468519421001725), (10.1016/j.mtchem.2021.100592))

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Editor-in-Chief. Following image duplication concerns raised by the community, Materials Today Chemistry agreed to the publication of a Corrigendum (Mater. Today Chem. 36 (2024) 101955, https://doi.org/10.1016/j.mtchem.2024.101955) to replace FESEM images that duplicated previously published work. Unfortunately, further duplication concerns were raised regarding XRD and CV data in the original article. The Editor-in-Chief requested clarifications from the authors and asked for the raw data to address these concerns. However, the response and data provided were deemed unsatisfactory, confirming the issues around XRD and CV data. As a result, the Editor-in-Chief lost confidence in the integrity of the article and made the decision to retract it. All authors agreed to retract the paper. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
