The title of this paper is clear, and the aim of the work is written in simple language but it's so clear for the reader. Researchers here discuss their results as they work and in my opinion it's good. But there is the keywords are missing in this paper. The reference I think all of the references, which have been used were relevant and referenced correctly, but only the miss typing may be in the reference number 1 because put only p. followed by the number of the paper while for all the rest of the references is used pp. followed by number of page, as well as the researchers tried to use more recent references but still there are some old references that used here, because of, as you know some that corrosion field found since much years ago.

The introduction is clear. Instead of written DFT calculation in my opinion should write the simulation or theoretical calculation, but the process of the subject is clear and method have been used its valid, also all the variables parameters are defined and measured appropriately.

In the results and discussion section, all tables and figures are relevant and Cleary presented, using the SI units which is good, as well as, using the significant numbers. Author discussed all the results and gives an enough discussion.

The conclusion is good give the answer of the goal of this work but I think the conclusions for the research article should or prefer to writ as paragraph not as points.

Overall, the paper is satisfied for the conditions.
