Expression of concern for ‘Solar-driven photodegradation of 17-β-estradiol and ciprofloxacin from waste water and CO2 conversion using sustainable coal-char/polymeric-g-C3N4/RGO metal-free nano-hybrids’ by Amit Kumar et al., New J. Chem., 2017, 41, 10208–10224, https://doi.org/10.1039/C7NJ01580A.
Concerns were first raised with the reliability of the XRD data in Fig. 2 and the UV-Vis data in Fig. 12c and Fig. 12d. The authors provided a response to address these concerns, however, they have not been able to provide the original raw XRD data and UV-Vis data for this article.
The Royal Society of Chemistry has asked the affiliated institution (Shoolini University) to investigate this matter and confirm the integrity and reliability of the XRD data reported in Fig. 2 and Fig. S6 and the UV-Vis data in Fig. 7c, Fig. 12c and Fig. 12d of this article.
An expression of concern will continue to be associated with this manuscript until we receive information from the institution on this matter.
