Abstract
Expression of concern for ‘Visible light driven photocatalytic oxidation of thiols to disulfides using iron phthalocyanine immobilized on graphene oxide as a catalyst under alkali free conditions’ by Pawan Kumar et al., RSC Adv., 2014, 4, 50331–50337, https://doi.org/10.1039/C4RA10128F.
RSC Advances is publishing this expression of concern in order to alert our readers that we are presently unable to confirm the reliability of the conclusions presented in the article due to concerns that insufficient characterization data was provided.
An investigation is underway, and an expression of concern will continue to be associated with this article until a final outcome is reached.
