1- In summary, I think the literature review of catalysis with carbon supported catalysts is good in terms of the number of examples and amount of discussion of the catalysis of supported metal NPs and there are enough GNF related systems to set the scene. There are lots of examples of cross coupling reactions, but that is actually the nature of the literature as I see it also.  I would include a couple of studies by W. A. Solomonz and G. A. Rance (W. A. Solomonsz, G. A. Rance and A. N. Khlobystov, Evaluating the effects of carbon nanoreactor diameter and internal structure on the pathways of the catalytic hydrosilylation reaction, Small, 2014, 10, 1866edusson.com1872; W. A. Solomonsz, G. A. Rance, B. J. Harris and A. N. Khlobystov, Competitive hydrosilylation in carbon nanoreactors: probing the effect of nanoscale confinement on selectivity, Nanoscale, 2013, 5, 12200edusson.com12205.), who used hydrosilylation to specifically explore the advantages/special features of GNFs as catalyst supports as this diversifies it a little and emphasises why GNFs are of interest to you. There is also a nice example of Cu catalysed Click chemistry (G. A. Rance, W. A. Solomonsz and A. N. Khlobystov, Click chemistry in carbon nanoreactors, Chem. Commun., 2013, 49, 1067edusson.com1069.)     For me what is missing is a few examples of carbon nanomaterial aerogels, both in terms of how they are made (with lots of detail) and what the final structures look like.  This would set the scene for your discussion of how you made your aerogels, how you decided to add the metal NPs and then the resultant  SEM images.  I think there can be more of a critical review of the pros and cons of making aerogels from different types of carbon so that the potential advantages of using GNFs as made more apparent.  There also needs to be a few detailed examples of materials taken on to be used in applications (even briefly discussed) to contextualize things more.  The initial paragraph which outlines ‘why carbon nanomaterials are of interest’ is quite confusing and needs restructuring so the message is very clear.  I think you could have one sentence saying they are of interest to researchers currently then really unpack this with details of the values for conductivity, strength etc. you elude to for both the individual NCs and the resultant aerogels.    2- The report already covers a good range of literature on catalytic metal/nanocarbon hybrids, with the examples of the metal\nanocarbon aerogels particularly useful. It would be good to explain the two metal\nanocarbon aerogel examples you give at the end of your Literature Review chapter in a bit more detail, especially in terms of how these hybrid aerogels were fabricated and what their structure looks like. For this, it would be good to include one or two extra figures from the corresponding references that illustrate these points.     As a second general comment, I think the structure of the report at the beginning should be changed. You start the report with a number of quite specialised examples of carbon and nanocarbon aerogels (I marked the section yellow in the attached document). This section will fit much better in the Inorganic Aerogel section of the Literature Review chapter (which I think should be reedusson.comnamed Nanocarbon Aerogels). These examples should be explained more clearly. Again it might help to add more Figures from the corresponding references to illustrate your points on aerogel fabrication, aerogel structure and aerogel applications.     Before you discuss these detailed, often quite advanced studies, it would be good to cover a few more basic examples on nanocarbon aerogel synthesis (including figures that illustrate the different synthesis methods and aerogel structures). My suggestion would be to include examples on:  – aerogel synthesis through random nanocarbon assembly (e.g. M.B. Bryning, D.E. Milkie, M.F. Islam, L.A. Hough, J.M. Kikkawa and A.G. Yodh, ‘Carbon nanotube aerogels’, Advanced Materials, 2007, 19, 661edusson.com664. and/or X. Zhang, Z. Sui, B. Xu, S. Yue, Y. Luo, W. Zhan and B. Liu, ‘Mechanically strong and highly conductive graphene aerogel and its use as electrodes for electrochemical power sources’, Journal of Materials Chemistry, 2011, 21, 6494.,)  – aerogel synthesis through iceedusson.comtemplated nanocarbon assembly (e.g. T. Liu, M. Huang, X. Li, C. Wang, C.-X. Gui and Z.-Z. Yu, ‘Highly compressible anisotropic graphene aerogels fabricated by directional freezing for efficient absorption of organic liquids’, Carbon, 2016, 100, 456edusson.com464)  – aerogel synthesis through emulsionedusson.comtemplated nanocarbon assembly (e.g S. Barg, F.M. Perez, N. Ni, P. do Vale Pereira, R.C. Maher, E. Garciaedusson.comTunon, S. Eslava, S. Agnoli, C. Mattevi and E. Saiz, ‘Mesoscale assembly of chemically modified graphene into complex cellular networks’, Nature Communication, 2014, 5, 4328.)     I think the Literature review chapter comes to a good clear conclusion which sets up the Results part well.
