Graphene-Based Materials as Efficient Photocatalysts for Water Splitting
Round 1
Reviewer 1 Report
The paper is a nice review on the use of graphene-based materials for water splitting.
It is well organized and I recommend acceptance after editing the following:
- More attention has to be given to the comparative performance of graphene-modified photocatalysts and graphene-free photocatalysts, possible introducing a table/figure in the manuscript with the most relevant results in terms of hydrogen evolution.
- The recent review by L.Y. Ozer et al., JPhotochemPhotobiolC, 2017, 33, 132-164, should be cited. It reports on the use of composites made of inorganic semiconductors and graphene for photo(electro)catalytic applications, including hydrogen production.

A new Table (Table 1) has been introduced in page 11 of the revised manuscript. This table contains some of the most relevant examples of defective G-based photocatalysts for H2 evolution and showing the reaction conditions.

Reviewer 2 Report
The authors provided a concise but thorough summary of the titled field. I believe that a comparison of benchmark G-based systems and other representative catalytic systems, including reaction condition, additive(s), catalytic efficiency, etc., will be valuable for the topic. Moreover, a summary/outlook of unique catalytic mechanisms in G-based systems compared to other catalytic systems will significantly benefit readers as well.

A summary of the most representative photocatalytic systems has now been included in Table 1. This table contains H2production rates, reaction conditions and light source.
A summary of the unique catalytic properties of graphene based materials has been included in section 5: conclusions and future prospects.
