Abstract
Expression of concern for ‘Reduced graphene oxide nanosheets decorated with Au, Pd and Au–Pd bimetallic nanoparticles as highly efficient catalysts for electrochemical hydrogen generation’ by Gitashree Darabdhara et al., J. Mater. Chem. A, 2015, 3, 20254–20266, https://doi.org/10.1039/C5TA05730B.
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 data. The Royal Society of Chemistry has asked the corresponding authors' institutions to investigate this matter. An expression of concern will continue to be associated with the article until we receive conclusive evidence regarding the reliability of the reported data.
