▎ 摘 要
We stress that the extraordinarily large adsorption energy and the large charge transfer to the adsorbate for the glucose adsorption structure of Ref. [1] are the results of adsorption of a C6H1O6 molecule rather than the adsorption of a glucose molecule. We report the glucose adsorption structure, the effect of Ni clusters on the adsorption energy of glucose, and the charge distribution for the glucose/Ni-13/Gr system. (C) 2019 Elsevier Ltd.
