Abstract
Expression of concern for ‘Monodisperse CuB23 nanoparticles grown on graphene as highly efficient catalysts for unactivated alkyl halide Heck coupling and levulinic acid hydrogenation’ by Shi Yan Fu et al., Catal. Sci. Technol., 2015, 5, 1638–1649.
Catalysis Science & Technology is publishing this expression of concern in order to alert our readers that we are presently unable to confirm the accuracy of the data reported in Fig. 1 of this paper and Fig. S1b, S3a and b, S22a–c, S24a and S25a of the ESI.
An investigation is underway, and this notice will be updated when a final outcome is reached.
