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

The SEM image in Fig. 1C duplicates data published in another publication, but reported as different materials.[1]

There are unexpected similarities in the XPS spectra presented for M1–rGO and M5–rGO in Fig. 2A.

Repeating fragments can be observed in the baseline of the XRD spectrum for GO presented in Fig. 2B, which indicate that it has been manipulated. In addition, the XRD spectrum for M5–rGO in Fig. 2B duplicates data published in ref. 1 and 2, but they have been reported as different materials.

Given the number and significance of the concerns about the validity of the data, the findings presented in this paper are no longer reliable.
