Fabrication of Metal/Carbon Nanotube Composites by Electrochemical Deposition
Round 1
Reviewer 1 Report
Dear Author
Please find enclosed the review report to the manuscript submitted entitled "Fabrication of Metal/Carbon Nanotube Composites by Electrochemical Deposition".
The review entitled “Fabrication of Metal/Carbon Nanotube Composites by Electrochemical Deposition” is focused on the fabrication process of metal-CNTs composites through two electrochemical deposition methods: electrodeposition and electroless deposition.
This review presents a well-structured introduction, leading the reader to understand the main focus of this review. The paper is well written and carefully divided into subchapters for the readers to easily understand and to be easy to follow. The topic covered in the review is widely supported by the relevant expertise of the author in material processing and microstructural control engineering and structural/functional materials using electrochemical approaches.
I recommend this article for publication with minor suggestions addressed to works that might help to enrich this review for future publication:
- In Line 291, the author refers the publication reported by Pereira et al., regarding the electrodeposition of Co/MWCNT composite films. In order to enrich the information provided in this paper, it would be important to address more research focused on non-aqueous electrolytes such as deep eutectic solvents (and ionic liquids) for the electrodeposition of metals on the MWCNTs matrix (which is demonstrated that it favours the carbon allotropes dispersion). Several papers have been published on the topic of metal-carbon composites using DES and ILs, so I think that this topic should be addressed. Below it is provided some papers that should be included in the main text:

Section 2.4.2
The authors did not mention the work reported by Raja et al. focused on the electrodeposition of Cu–SWCNT Composites. The authors used a direct current electrodeposition and varied the CNT proportions without use surfactants or dispersing agents, or neither functionalizing the SWCNTs.

2.4.8. Other metal/CNT Composites
Carbon–tin composite materials was reported by Brandão et al. in which it was incorporated oxidized multi-walled carbon nanotubes (ox-MWCNT) and pristine multi-walled carbon nanotubes (P-MWCNT) into a metallic tin matrix using electrodeposition in deep eutectic solvents composed by choline chloride and ethylene glycol.
