Retraction Note: Investigating the Heteronjunction between ZnO/Fe₂O₃ and g-C₃N₄ for an Enhanced Photocatalytic H₂ production under visible-light irradiation

Retraction of: Scientific Reports https://doi.org/10.1038/s41598-019-48730-z, published online 27 August 2019

The Editors have retracted this Article.

After publication the Editors were made aware of concerns about the data presented. Specifically:

• There are four similar XRD patterns in Figure 2a (7-ZnO/Fe ~ 2 ~ O ~ 3 ~ /g-C ~ 3 ~ N ~ 4 ~ , 5-ZnO/Fe ~ 2 ~ O ~ 3 ~ /g-C ~ 3 ~ N ~ 4 ~ , 3-ZnO/Fe ~ 2 ~ O ~ 3 ~ /g-C ~ 3 ~ N ~ 4 ~ and 1-ZnO/Fe ~ 2 ~ O ~ 3 ~ /g-C ~ 3 ~ N ~ 4 ~);

• The XRD patterns appear to be similar between Figure 2a and Supplementary Figure S8a.

In addition, there are similarities between figures in this Article and in another publication¹ by the same author group. Specifically:

• Figure 2b appears to be similar to Figure 1b in¹ where different compounds are used;

• Figure 6c appears to be similar to Figure 5c in¹ where different compounds are used.

The Editors therefore no longer have confidence in the reliability of the data presented.

Na Mao agrees with this retraction.
