Reviewer 3 Report
This paper describes electrochemical glucose oxidation catalyzed by B-N codoped graphene quantum dots. Development of GOR catalyst without transition-metal is significant because direct oxidation glucose fuel cell supplys the necessary energy for implanted medical devices. In this paper, authors have reported B-N co-doped GQD prepared by a simple solvothermal method shows relatively high catalytic activity for electrochemical GOR. So, this manuscript is basically of potential interest for the readership of Catalysts. However, performance of the B-N co-doped GQD as a GOR catalyst is not clear. Therefore, I would like to decide my recommendation of this paper after the authors have addressed the following points.
Major points
- To clarify catalytic performance of N-doped and B-N co-doped GQD, authors must show the results of controlled-potential electrolysis of a glucose solution at several potentials in main text. Time variation of current density (A cm-2) clearly indicates catalytic activity and stability of the catalysts.
- Figure 6 of P8. Authors should explain the reason why the current increase with increase of scan cycle of CV.
Minor points
- Figure 6 of P8. To clearly compare N-doped and B-N codoped GQD, current density of Figure 6a and 6b should be displayed by same scales.
