3-Dimensional Porous Carbon with High Nitrogen Content Obtained from Longan Shell and Its Excellent Performance for Aqueous and All-Solid-State Supercapacitors

Round 1

Reviewer 1 Report

In this study, authors report the production of carbon materials from longan shell by simple carbonization and then the interconnected 3-dimensional porous structure was obtained via KOH activation treatment. This work demonstrates its application as active material in aqueous and all-solid-state supercapacitor. In terms of the electrochemical performance, as-prepared porous carbon from longan exhibits high electrical performance. I recommend to publish this manuscript in Nanomaterial after minor changes.

1. Authors claimed that the carbon obtained from longan bio-source is rich in nitrogen, leading the its high electrical conductivity. The electrical conductivity results should be added in the manuscript to ensure N effect. 
2. Please check Figure numbering in the text (ig. 4 and 6)

Reviewer 2 Report

Liu et al have synthesized nitrogen doped carbon from longan shell. I highly appreciate the authors for enriching the manuscript with lot of data. The data presentation and the results section is well discussed. I highly recommend this article to be published in Nanomaterials journal without any further modifications.
