Abstract
Retraction of ‘A surfactant-free co-assembly route to fabricate 2D TiO2–WO3 composite inverse opal films for photochromic applications’ by Hongyu Zhen et al., New J. Chem., 2014, 38, 4041–4044.
We, the named authors, hereby wholly retract this New Journal of Chemistry article.
In this article we report a method to fabricate 2D TiO2–WO3 composite inverse opal films via a mechanical co-assembly route with a template of polystyrene spheres. Upon repeating the experiments described, we found that this was not an effective method for forming the films; often the film was broken or did not form at all. We suggest that this may be due to the mechanical forces exerted by the rubber, which were inconsistent between experiments and predominantly acted in one direction only. Therefore we are no longer confident that the method and results reported in this article are reliable. We retract this article to avoid misleading readers and apologise for any inconvenience caused to New Journal of Chemistry and the readers.
