Research Progress on Application in Energy Conversion of Silicon Carbide-Based Catalyst Carriers

Round 1

Reviewer 1 Report

In this manuscript, the authors reviewed the progress in preparations and catalytic applications of high specific surface area SiC. After glancing over the manuscript, I do not recommend it to be published in the present form.

1.      There are several important review articles/book about SiC preparations and catalytic applications published recently, but these authors did not cite them. These articles include:

(1)    Chemical Reviews, 2021, 121, 10559−10665: Porous Silicon Carbide (SiC): A Chance for Improving Catalysts or Just Another Active-Phase Carrier?

(2)    Catalysis Reviews (2021, https://doi.org/10.1080/01614940.2022.2025670), Silicon carbide in catalysis: from inert bed filler to catalytic support and multifunctional material.

(3)    Guo XY, High Specific Surface Area Silicon Carbide, Chemical Industry Press: Beijing, 2020.

Earlier review articles:

(1)    Progress in Chemistry, 2014, 26: 502, Silicon carbide as a novel support for heterogeneous catalysis

Since the authors did not read the above articles/book, it is difficult to tell readers the whole progress about SiC preparations and catalytic applications.

2.      The classification of preparation methods is not clear. For example, in “2.1 Carbothermic reduction method”, the method described by Qian et al in Ref[27] has no any relation with the carbothermic reduction, it belongs to solvothermal synthesis.

3.      As for the “ Sol-gel method”, Jin et al firstly described a sol-gel route, and employed it to prepare high specific surface area SiC ( Micropor. Mesopor. Mater., 2003, 60: 207). Afterword, Zheng et al (Scripta Materialia, 2006, 55: 883) and others further developed the sol-gel route. In this manuscript, the authors did not cite the above Refs, but began form Ref. [28], which was published in 2008. Other Refs cited in this part were published more latterly.

4.      In lines 446-447, the authors cited [73-75] to explain the synergistic effects between metal and SiC. I feel that the authors wanted to say should be “ charge-transfer effect”(Mott-Schottky effect).  The Mott-Schottky effect or charge-transfer effect between metal and SiC was early reported by Jiao et al (Ref[78]) in 2014 rather than Ref.[73-75]. I do not suggest that the authors use “synergistic effect” here. However, Ref [74] by Hao et al reported a novel synergistic effect generated by SiC and SiC-supported Au and Pd nanoparticles.

Dear Reviewer,

Thank you very much for your comments and suggestions, they helpe me a lot.

     Here are the details of my modifications:

Reviewer 1:
1. There are several important review articles/book about SiC preparations and
catalytic applications published recently, but these authors did not cite them. These articles include:
(1) Chemical Reviews, 2021, 121, 10559−10665: Porous Silicon Carbide (SiC): A
Chance for Improving Catalysts or Just Another Active-Phase Carrier?
(2)Catalysis Reviews (2021, https://doi.org/10.1080/01614940.2022.2025670),
Silicon carbide in catalysis: from inert bed filler to catalytic support and
multifunctional material.
(3) Guo XY, High Specific Surface Area Silicon Carbide, Chemical Industry Press:
Beijing, 2020. Earlier review articles:
(1) Progress in Chemistry, 2014, 26: 502, Silicon carbide as a novel support for
heterogeneous catalysis
Since the authors did not read the above articles/book, it is difficult to tell readers the whole progress about SiC preparations and catalytic applications.

Response: The four requested documents have been added, which are:
1. Wang, Z. J.; Fu, Q.; Bao, X. H. Silicon Carbide as a Novel Support for Heterogeneous Catalysis. Progress in Chemistry, 2014, 26, 502-511.
2. Tuci, G.; Liu, Y. F.; Rossin, A.; Guo, X. Y.; Pham, C.; Giambastiani, G.; Cuong, P. H. Porous Silicon Carbide (SiC): A Chance for Improving Catalysts or Just Another Active-Phase Carrier? Chemical Reviews, 2021, 121, 10559-10665.

103. Guo, X. Y. High specific surface area silicon carbide.; Chemical Industry Press: Beijing, China, 2020; pp. 49-74.

2. The classification of preparation methods is not clear. For example, in “2.1
Carbothermic reduction method”, the method described by Qian et al in Ref[27] has no any relation with the carbothermic reduction, it belongs to solvothermal synthesis.

Response: Ref[27] has been modified in the “2.1 Carbothermic reduction method” section of the text. Ref[27] was deleted and its attachment content is adjusted.

3. As for the “Sol-gel method”, Jin et al firstly described a sol-gel route, and
employed it to prepare high specific surface area SiC ( Micropor. Mesopor. Mater., 2003, 60: 207). Afterword, Zheng et al (Scripta Materialia, 2006, 55: 883) and others further developed the sol-gel route. In this manuscript, the authors did not cite the above Refs, but began form Ref. [28], which was published in 2008. Other Refs cited in this part were published more latterly.

Response: It has been modified in the "Sol-gel method" section of the text and
introduced into these two articles, respectively:
33. Jin, G. Q.; Guo, X. Y. Synthesis and characterization of mesoporous silicon carbide. Microporous and Mesoporous Materials, 2003, 60, 207-212.
34. Zheng, Y.; Zheng, Y.; Lin, L. X.; Ni, J.; Wei, K. M. Synthesis of a novel mesoporous silicon carbide with a thorn-ball-like shape. Scripta Materialia, 2006, 55, 883-886.

4. In lines 446-447, the authors cited [73-75] to explain the synergistic effects
between metal and SiC. I feel that the authors wanted to say should be
“ charge-transfer effect”(Mott-Schottky effect). The Mott-Schottky effect or
charge-transfer effect between metal and SiC was early reported by Jiao et al (Ref[78]) in 2014 rather than Ref.[73-75]. I do not suggest that the authors use “synergistic effect” here. However, Ref [74] by Hao et al reported a novel synergistic effect generated by SiC and SiC-supported Au and Pd nanoparticles.

Response: The "synergistic effect" in this section has been replaced by "charge
-transfer effect". The Ref [74] of Hao et al. is quoted here to introduce two cases of SiC supported active phase: loaded monometallic and loaded bimetal, and Ref[74] is SiC loaded bimetal (Au and Pd), thus further illustrating the current research on SiC supported metal active phase.

Reviewer 2 Report

There has a least two famous review articles concerning the synthesis and applications (especially for catalysis) of porous Silicon carbide. For example: Chemical Reviews, 2021, 121, 17, 10559–10665; Catalysis Reviews, 2022, doi.org/10.1080/01614940.2022.2025670. The recent new results and improvements in the field of the silicon carbide have not been summarized. Surprisingly, the above mentioned two review articles have not been discussed in this review. Thus, I cannot recommend it to be published.

Reviewer 5 Report

The application of SiC in catalysis is reported in detail in this review, especially in SiC-based catalyst carriers. The in-depth analysis indicated that the construction of SiC with a special structure, large-scale synthesis of SiC by utilizing waste materials, and low-tempera- 24 true synthesis of SiC has been discussed. This work has made significant contributions to this field. I would like to recommend that this review be published in Catalyst.

Reviewer 6 Report

The paper summarizes state-of-the-art in the silicon carbide-based catalyst carriers to be used for the energy conversion.

The topic is relevant and can be of interest for the wide range of scientific community involved in both catalysts research and development and in the creation and application of novel silicon-carbide-based materials

The review range over a number of different aspects of the topic connected with processing techniques, raw materials, structure-properties relations and includes the appropriate citations and coherent conclusions.

The presentation of cases is understandable and consists of enough details, although generalized properties of silicon carbide and some intermediate conclusions are repeated in different sections, which seems to be somewhat excessive.

And I found few points to be addressed:

Page 3, line 130. The expression “the obtained SiC microcrystals can serve as crystal nuclei” sounds incorrect for me. I suggest to replace “micro-“ with “nano-” or to remove it at all.

Page 4, Fig.1. The designations of SiC nanofibers and nanoparticles in Fig. 1 look contrariwise. Please, check it.

Page 16, line 711. The sentence “The higher specific surface area of the  NiMgAl/SiC composite catalyst led to the formation of smaller Ni NPs on the carrier, which is beneficial for obtaining high activity in the methanation of CO2” seems to be confusing after the order  NiMgAl > NiMgAl/SiC > Ni/SiC mentioned previously. I recommend to rewrite this sentence to make it clear which is the best (better) and as compared to what.

Page 17, line 760.  I think it is better to use the plural in the expression “the author has several views … “ in conclusion

Therefore, I recommend a minor revision
