Retraction: Design and synthesis of magnetic Fe₃O₄@NFC-ImSalophCu nanocatalyst based on cellulose nanofibers as a new and highly efficient, reusable, stable and green catalyst for the synthesis of 1,2,3-triazoles

Abstract

Retraction of ‘Design and synthesis of magnetic Fe₃O₄@NFC-ImSalophCu nanocatalyst based on cellulose nanofibers as a new and highly efficient, reusable, stable and green catalyst for the synthesis of 1,2,3-triazoles’ by Pouya Ghamari kargar et al., RSC Adv., 2020, 10, 32927–32937, https://doi.org/10.1039/D0RA06251K

The Royal Society of Chemistry, with the agreement of the named author, hereby wholly retracts this RSC Advances article due to concerns with the reliability of the data.

The XRD patterns in Fig 4a–c and 10b contain repeating sections. The authors provided raw data for Fig. 4, but this was found to contain duplicated sections of data across different datasets representing different samples.

The raw XRD data provided by the authors for Fe₃O₄ in Fig. 4a of this article was identical in a number of different regions to the raw XRD data provided by the authors for CuO in Fig. 4b of this article and Fig. 3 of ref. 1. In Fig. 4c, the XRD data for Fe₃O₄@NFC-ImSalphCu was also found to contain identical sections of data within the raw dataset.

The authors have stated that they outsourced the XRD data collection to an external company.

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

The authors were informed about the retraction of the article. Pouya Ghamari Kargar and Ghodsieh Bagherzade have not agreed with the decision.
