Comments on abstract, title, references

Starting with the title, it is quite striking, which makes any person, that is to say who does not have good knowledge of the subject becomes interested, so it is a positive thing, since it must engage the reader, to continue reading about their research, now let us consider the people who are related to these topics, it will be very helpful to expand knowledge, and understand more about it.

As for the abstract, you need to improve a little, mention a little more of the properties of catalysts, ie expand a little more, to have a clearer perspective on the article.

Although the article itself shows an advance of research to be more viable the process of using organic polymers to obtain fuel from water, using catalysts and dividing hydrogen from water and reducing the carbon footprint of the fuel, which would be a very big advance, however it must be considered how feasible this process is and propose a brief comparison on the fuel we use now with it that is proposed in the article.

An interesting aspect mentioned in the article is "the division of water induced by light into oxygen and hydrogen" since what is desired is an alternative to reduce the carbon footprint, which is produced with the current fuel and be able to reduce environmental pollution, so having the perspective that new research is presented to be able to change the environmental impact, it is of great satisfaction, far above that it is still underway, You should also consider that although it sounds very encouraging you need photocatalysts and co-catalysts such as platinum you other noble metal to really see good results, and also that its efficiency is high, but that is not yet achieved.

Comments on introduction/background

Certainly the introduction of this article is striking and really focuses on making known the process of obtaining separation of water and is supported by literature material to make us aware of the importance of the subject, so we are illustrating little by little, as the resource could be obtained to obtain the expected product, letting us understand that a resource like the sun could obtain the separation of water, which is just what we would like to achieve for fuel, And reduce the carbon footprint itself.

Comments on methodology

In paragraph number one of the article, but how does it potentially resolve the world's energy demands? , a few inorganic catalysts should also be mentioned which are referred to in the paper. So based on paragraph two, what would be the alternative for the design of photocatalytic materials to work as expected, it is really feasible to want to use this method for obtaining fuel. We have in itself, that the whole article is based on showing us the studies of sprick, which shows in detail the techniques that I use to measure the percentage of efficiency of the methods that are being used to be more profitable and effective, the method to obtain fuel by means of organic polymers. Among the strengths of the article, are the ingenuity of showing ongoing research, to

Comments on data and results

Among the graphs shown in the article we have that have their names, indicating what represents each axis, and has its explanation as such, so this gives us a greater teaching regarding the data on the research carried out The article itself shows the results obtained from another document, already cited, but should put more analysis with data, to better support the article, and be more proportionate. I believe that more statistical information on photocatalysts is needed in order to have more insight into the subject. Another suggestion about the time of performance of the electron donors, and which more would be favorable for them.

Comments on discussion and conclusions

As for the conclusion, I needed to elaborate a bit more and not to take for granted some things, for example, give some Suggestions of how photocatalysts help water separation, what more methods can be given, although the article poses a research in development should be given more information and give a brief comparison with the fuel we use today
