B and N Co-Doped Wood Scrap Charcoal for Decorated Supercapacitor with High Conductivity

Round 1

Reviewer 1 Report

In this work, the authors had presented their work on boron and nitrogen co-doped activated carbon for supercapacitor applications. Detailed methodology is provided in this work and the electrochemical performance of the activated carbon shows the materials exhibited electrochemical capacitive behaviour in three electrode system and two electrode symmetrical supercapacitor device. However, some of the suggestions must be considered before accepted for publication.

2. What is the mass loading of sample on the nickel foam and what is the electrolyte used in this study?

3. The elemental mapping images of BNPCM show include the scale bar and the original SEM image as reference.

4. Why does the PNCM has higher higher ID/IG ratio than NCM?

5. What is the possible redox reaction occurred on the B and N groups in the electrode?

6. The electrochemical performance such as EIS and cyclic stability of the SSC should be added in this study to compare its performance in 3 electrode system.

Round 2

Reviewer 1 Report

The author had made all the changes based on the comments and suggestions. But there is one error on the redox equation (below). The hydrogen in left side and right side of equation is not balanced.

C*-B-C=O+2e⁻⟷C*-B-CH-OH 

Author Response

Thanks for the comment. The redox equation has been corrected as follows:

C*-B-C+2H⁺=O+2e⁻⟷C*-B-CH-OH  

and the correction has been highlighted in the revised manuscript.
