Abstract

Retraction of ‘Iron-selenide-based titanium dioxide nanocomposites as a novel electrode material for asymmetric supercapacitors operating at 2.3 V’ by Muhammad Zia Ullah Shah et al., Nanoscale Adv., 2023, 5, 1465–1477, https://doi.org/10.1039/D2NA00842D.


The Royal Society of Chemistry hereby wholly retracts this Nanoscale Advances article due to concerns with the reliability of the data.

The XRD patterns and Raman data in Fig. 1, and the EDX data in Fig. 3 were first published in ref. 1 by different authors. The SEM data in Fig. 2b is partially identical to data published in ref. 1 and has signs of being edited.

The authors provided a response, but it did not address the concerns. The authors were unable to provide the raw data.

Given the significance of these concerns, the findings presented in this paper are no longer reliable.

The authors did not respond to any correspondence regarding the retraction of this article.
