Editorial Expression of Concern to: Reac Kinet Mech Cat (2016) 117:365–377 https://doi.org/10.1007/s11144-015-0943-z
The Editor-in-Chief would like to alert readers that concerns have been raised regarding the image overlap of Fig. 2a of this article with other published articles authored by some of the same authors. Figure 2a in this article depicted an SEM image of nano titania-supported sulfonic acid (n-TSA) before use as a nanocatalyst. The authors stated that image 2a in the article is incorrect and depicts TiO2 nanoparticles. This mistake happened due to the same morphology of TiO2 nanoparticles and sulfonated nano TiO2 particles. The authors confirmed that this does not affect the core results of the article. Readers are advised to interpret the results with caution.
All authors agree to this EEoC.
