Feedback from New Page Review process

I left the following feedback for the creator/future reviewers while reviewing this article: for any catalyst how it is made and how it acts are completely different topics. This page conflates the two, suggesting that fabrication from plants somehow is different. It also tries to put under its umbrella well established approaches such as hydrothermal, microwave and sol-gel which existed well before there was any discussion of global warming. A major NPOV rewrite is needed.

Thank you for your insightful review and feedback. I understand your concern regarding the potential conflation of synthesis methods with catalytic activity and the perceived implication that established methods like hydrothermal, microwave, and sol-gel are inherently "green" simply by being mentioned in this context. I appreciate you bringing this to my attention, and I believe I can clarify the intended scope and focus of the article.

The core subject of this article is "green photocatalysts," where "green" signifies the utilization of environmentally benign and sustainable precursors derived from biological sources, like plants, for the synthesis of photocatalytic nanoparticles. This aligns with the principles of green chemistry, specifically green sourcing and process modification, as highlighted in the primary inspiration to this article: Naushad, Mu., Rajendran, S., & Lichtfouse, E. (Eds.). (2020). Green Photocatalysts. Springer International Publishing. This approach is further supported by articles like Singh, J., Dutta, T., Kim, KH. et al. ‘Green’ synthesis of metals and their oxide nanoparticles: applications for environmental remediation. J Nanobiotechnol 16, 84 (2018), which emphasizes the use of biological entities in nanoparticle synthesis for environmental applications.

The article's intention is not to claim that established synthesis methods themselves are inherently "green." Rather, it explores how these methods can be adapted and modified to incorporate green precursors, reducing or eliminating the reliance on hazardous chemicals and promoting resource efficiency. The novelty lies in the application of these methods using green reducing agents from the green sources, thereby minimizing the overall environmental impact of the synthesis process. The distinction is not about the method itself, but the materials used within that method.

To address your concerns and improve clarity, I will revise the article to explicitly emphasize this distinction between the source of materials and the catalytic function. The structure will be revised to clearly delineate the discussion of green precursors used in the synthesis process from the subsequent catalytic activity and applications of the resulting nanoparticles. This restructuring aims to provide a more accurate, balanced, and nuanced perspective on the topic of green photocatalysts, highlighting the role of sustainable practices in nanoparticle synthesis. I believe these revisions will address the NPOV concern and provide a more comprehensive understanding of the subject matter. Dhanidon.ggi (talk) 01:40, 12 November 2024 (UTC)

I am OK if you just focus on the precursor aspects, that I will accept as "green". I will monitor the changes you make, rather than confusing by making some myself. Feel free to ask for input. Ldm1954 (talk) 02:27, 12 November 2024 (UTC)

Reworked the lead a little bit, should be more clear Mrfoogles (talk) 09:05, 12 November 2024 (UTC)

It needed much more than a minor tweak. I have removed a large amount of non-NPOV material. It is very inappropriate to make claims about conventional photocatalysis being "worse" or citing "green chemistry" as if this was a law. Just stick to the facts and don't add opinions please.
