Reviewer 1 Report

Comments and Suggestions for Authors

This paper analyzes Anode materials for microbial fuel cells- devices that directly convert chemical energy into electrical energy using organic matter as its raw material. 

Overall, we think that this is a meaningful work and can be publishable in this journal after minor revisions.

1.    We believe that in the introduction, readers would like to see a more extended overview of the world level of development of the MFC.

2.     From the description of the Figure 3. Performance of MFCs with S/CNT and S/CNT/PANI/CS anodes: (a) power density and (b) 236 polarization curves of the corresponding MFCs and Figure 4. Chronopotentiometry of MFCs with S/CNT and S/CNT/PANI/CS anodes under different 253 charging time conditions (a–c: charging time: 15–60 min) it is unclear at what temperature and relative humidity the measurements were carried out. 

3.    In our opinion, Figure 7. Phylum distributions of the microbial communities on the (a) modified anode and (b) the control anode is currently difficult to understand; we recommend formatting it (for example, increasing the text font and changing the colors). 

4.    English can be improved.

Good work. Please, keep it up.

 

Line 188: Please quantify, 

how much high amount of active material promotes known electron transfer

Line 275:  Please, rewrite   …. Give values “This provides

ample power for high-power electrical devices, effectively addressing the issue of low MFC output power   ….  

Line 311: Please give the mechanism,

i)                    how the presence of CNT increases the electron transfer what happened to impedance

ii)                  in parallel, how PANI works in reduction of impedance while CNT is working

Title: 3D Porous Sponge/Carbon Nanotube/Polyaniline/Chitosan Capacitive Bioanode Material for Improving the Power Generation and Energy Storage Performance of Microbial Fuel Cells

Journal: Coatings

ID: coatings-2813435-peer-review-v1

In this manuscript, the author has reported the Power Generation and Energy Storage Performance of 3D Porous Sponge/Carbon Nanotube/Polyaniline/Chitosan capacitive bioanode based microbial Fuel Cells. The parameters of performance are adequately described in the abstract. Sufficient background and details are provided in the introduction. Experimental methods are described well. The results are thoroughly described and well presented. Conclusions include main findings of the work. However, there are following issues which should be addressed before the publication of the manuscript.

 

  1. Two composites: S/CNT, S/CNT/PANI/CS are studied in this work. Why did not consider intermediate compositions such as S/CNT/PANI or S/CNT/CS? From the two compositions studied in this work, it is not possible to say whether the change in properties is due to PANI or CS or both. Means, individual contribution of PANI and CS to the enhancement of properties of S/CNT. This issue should be addressed in the manuscript.
  2. The highest values of the remaining parameters such as power density, Rct etc should be included in Table 1.
  3. The comparison of the values of different parameters obtained in this work should be compared with the previously reported values possibly by making a comparison Table.
  4. The font size used in Fig. 7 to indicate different sections is very small. It should be increased to a readable font size.
  5. The manuscript should be thoroughly revised for grammatical errors and English language corrections.
