Catalyst Development for Biogas Dry Reforming: A Review of Recent Progress
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis paper provides an overview of the state-of-the-art development of biogas dry reforming catalysts, including categories of recently advanced catalysts and their strategies for addressing coking and sintering issues. The topic is relevant, and the discussion is comprehensive. The paper could be published once the following questions are thoroughly addressed.
1. The authors may double check the format of the references. Some references didn't include the page number (i.e. [13], [16]). Just making sure all the references format are consistent.
2. Could the authors briefly discuss why the biogas dry reforming may outperform classical dry reforming? Since the 2000s, the shale gas revolution has produced substantial amounts of shale gas, keeping classical dry reforming competitive.
3. Should the authors consider adding a sub-section for the current theoretical computation (i.e. DFT calculations) findings and reaction mechanism study of the biogas dry reforming catalysts?
4. It's might be a good idea to using a table or graph to summarize the state-of-art biogas dry reforming catalysts performance for comparison. (e.g. activity, selectivity)
5. In section 4 (Challenges and future trends), the author mentioned 'machine learning will be crucial'. Recently, the generative AI has been a hot spot in ML . The generative models like Transformer, Diffusion, and Generative Adversarial Nets (GAN) have been broad to the attention of the public. Maybe they could exceed the limitation for just predicting the performance and also generate the structures with high performance and help researcher understand what kind of structures possess high performance. Could the author utilize 3-4 sentences in the paper to talk about the future application of generative AI in dry reforming catalysts design?
Comments on the Quality of English LanguageThe authors may double-check for minor grammar mistakes. For example, in line 121, "et al." should follow three or more listed items.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe review covers various catalysts used in biogas dry reforming, including noble and non-noble metal catalysts. It does well to outline the challenges such as coking and sintering. It could be published on Catalysts after solving the following issues:
1) The introduction provides a robust context for the significance of biogas, yet it could be enhanced by incorporating more recent statistics and perhaps a brief discussion on the economic impact of improved biogas technologies, which would underline the practical relevance of the review;
2) The discussion adeptly synthesizes findings from recent studies, highlighting advancements in catalyst efficiency and stability. However, it reads like a list of studies rather than a cohesive narrative. Integrating these findings into a broader discussion about the implications for future technology development could provide more depth;
3) Consider including more graphical representations of the data, particularly reaction mechanisms and the effects of different catalyst modifications.
4) Provide more detailed and specific future research directions, particularly how new findings could be practically applied.
