Construction of layered hierarchical CoMoO4 nanostructured arrays for supercapacitors with enhanced areal capacitance

Layered hierarchical CoMoO4 nano-structured arrays grown on nickel foam were designed and synthesized by a two-step hydrothermal method following by annealing. With the increase in the nearly three times loading mass of active materials, the specific capacitance of the layered hierarchical CoMoO4 nano-structured arrays only shows a slight loss compared with the single-layer CoMoO4 nano-structured arrays, which dramatically improved the areal capacitance from 2.47 to 6.79 F cm−2. Also, the layered hierarchical CoMoO4 nano-structured arrays showed 94.8% capacitance retention after 2500 cycles, which is mainly due to the well-designed layered hierarchical structure and good conductivity.

To revise your manuscript, log into https://mc.manuscriptcentral.com/rsos and enter your Author Centre, where you will find your manuscript title listed under "Manuscripts with Decisions". Under "Actions," click on "Create a Revision." You will be unable to make your revisions on the originally submitted version of the manuscript. Instead, revise your manuscript and upload a new version through your Author Centre.
When submitting your revised manuscript, you will be able to respond to the comments made by the referees and upload a file "Response to Referees" in "Section 6 -File Upload". You can use this to document any changes you make to the original manuscript. In order to expedite the processing of the revised manuscript, please be as specific as possible in your response to the referees.
When uploading your revised files please make sure that you have: 1) A text file of the manuscript (tex, txt, rtf, docx or doc), references, tables (including captions) and figure captions. Do not upload a PDF as your "Main Document". 2) A separate electronic file of each figure (EPS or print-quality PDF preferred (either format should be produced directly from original creation package), or original software format) 3) Included a 100 word media summary of your paper when requested at submission. Please ensure you have entered correct contact details (email, institution and telephone) in your user account 4) Included the raw data to support the claims made in your paper. You can either include your data as electronic supplementary material or upload to a repository and include the relevant doi within your manuscript 5) All supplementary materials accompanying an accepted article will be treated as in their final form. Note that the Royal Society will neither edit nor typeset supplementary material and it will be hosted as provided. Please ensure that the supplementary material includes the paper details where possible (authors, article title, journal name).
Supplementary files will be published alongside the paper on the journal website and posted on the online figshare repository (https://figshare.com). The heading and legend provided for each supplementary file during the submission process will be used to create the figshare page, so please ensure these are accurate and informative so that your files can be found in searches. Files on figshare will be made available approximately one week before the accompanying article so that the supplementary material can be attributed a unique DOI. ********************************************** RSC Associate Editor: Comments to the Author: (There are no comments.) RSC Subject Editor: Comments to the Author: (There are no comments.) ********************************************** Reviewer comments to Author: Reviewer: 1 Comments to the Author(s) The paper contains original material but is written unclearly. Overall, I think the paper can be accepted for publication in Royal Society Open Science if the authors should clarify the following unclear questions. 1) What's the thickness of the CoMoO4 nanoflower-like structures? Is there any relationship between the thickness and capacitance? I read the manuscript several times and found it very preliminary with little data. To optimize synthesis condition, I strongly suggest the authors make the performance comparison among more samples.
2) The title is unclear, and the English in text should be finely polished.

Comments to the Author(s) Hu et al described the fabrication of a layered hierarchical nano-structured CoMoO4 on nickel foam by a facile two-step hydrothermal reaction following annealing treatment and their applications for supercapacitor. The LH-CoMoO4 shows a high areal capacitance of 6.79 F cm-2, which is much higher than the SL-CoMoO4 of 2.47 F cm-2. The nanostructured LH-CoMoO4 exhibits good conductivity and excellent cycle performance, which confirmed the importance of nanostructures reported herein. This work affords an emerging and facile method to obtain advanced energy materials. The reason for the excellent performance is also demonstrated. This work is a very important contribution to Royal Society Open Science.
