Recent Advances in g-C₃N₄ Photocatalysts: A Review of Reaction Parameters, Structure Design and Exfoliation Methods

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Dear Authors,

I have reviewed your Review manuscript “Recent Advances in g-C3N4 Photocatalysts: A Review of Reaction Parameters, Structure Design and Exfoliation Methods” and expressed my positive feedback regarding your submission. You have explored a very interesting and important topic, but it should be pointed out more, so I request major revisions.

I have a few suggestions for revisions that I believe would further enhance the quality and comprehensiveness of the manuscript.

 ·        Addition of "Doping Strategies" Section:

I recommend including a dedicated section that discusses the various doping strategies used in g-C3N4 photocatalysis. This is an essential aspect of the research and will give readers a deeper understanding of the topic.

 ·        Expand "Applications of g-C3N4 Photocatalysts":

While you touch on applications briefly, it would be valuable to have a more in-depth exploration of the practical applications of g-C3N4 photocatalysts, such as their role in environmental remediation and the photodegradation of organic pollutants.

 ·        Integrate "Challenges and Future Directions" Section:

To provide a more comprehensive perspective, I suggest adding a section that outlines the challenges faced in g-C3N4 photocatalysis and discusses potential future directions and avenues for research.

These additions will help strengthen the paper and make it even more informative and valuable to readers. I understand this might require additional work, and I appreciate your efforts in advance.

Best regards

Reviewer 2 Report

Comments and Suggestions for Authors

In this manuscript, Yu et al. reviewed the recent advances in the synthesis and structural design of g-C₃N₄ materials.

1 1. I suggest the authors to change “graphitized carbon nitride” to “graphitic carbon nitride”, which is a more commonly used term within this area.

2 2. Line 77, the authors talked about the precursors for g-C₃N₄ synthesis, but only one example from ref.41 is discussed in detail. As a review, other papers with different precursors should also be included to support the claim that “various precursors such as … have been employed…”.

3 3. Add references for Line 78-80.

44. Line 204-226, provide more examples for hard template methods in addition to silica.

55. The authors talked about how different methods influence the surface area, bandgap and .... of g-C₃N₄ photocatalyst, however, more discussions about the photocatalytic performance are needed. In each section (e.g. 2.1. Precursors and Reaction Temperature; 2.2. C/N Ratio...), the authors should clarify how these factors affect the photocatalytic performance of g-C₃N₄. For instance, what bandgap width is considered "good" for photocatalytic activity? the narrower the better? What is the relationship between the C/N ratio and the photocatalytic activity of g-C₃N₄? Are there any related data from photocatalytic studies to support that these strategies are effective?

Reviewer 3 Report

Comments and Suggestions for Authors

In the review entitled "Recent Advances in g-C3N4 Photocatalysts: A Review of Reaction Parameters, Structure Design and Exfoliation Methods", Pei and co-workers described several factors contributing to the preparation and utilization as a catalytic material, the g-C₃N₄ nanoparticles. This is a comprehensive review of the subject and worth publishing in Catalysts. Only minor revision has to be done before publication:

1. In the case of large subsections (3.1 and 3.2), a small summary (e.g., bullet points) of the most important findings should be added at the end of each paragraph.

2. Please add to the Conclusions a paragraph about the best approaches and methods of obtaining high-active g-C₃N₄-based catalytic materials.
