Abstract
Expression of concern for ‘Ultrasound-assisted diversion of nitrobenzene derivatives to their aniline equivalents through a heterogeneous magnetic Ag/Fe3O4-IT nanocomposite catalyst’ by Reza Taheri-Ledari et al., New J. Chem., 2020, 44, 19827–19835, https://doi.org/10.1039/D0NJ05147K.
The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the reliability of the EDX spectra in Fig. 2a and b. An investigation is underway, and an expression of concern will continue to be associated with the article until a final outcome is reached.
