In attached Review article registered that in mononuclear
Ru-based WOCs hydrophilic/hydrophobic properties act as a barrier for coupling process of two radicals during water oxidation without any explanation about that. Now here is the question How can hydrophilic/hydrophobic properties affect the radical coupling process in WO's molecular catalysts? Is there any relation between hydrophilic/hydrophobic properties and radical coupling process ?
Article Frontiers of water oxidation: The quest for true catalysts
The review is relatively old. Much has been done for the last 4 years. The mechanism is highly speculative. I disagree with authors on numerous aspects. I think that there is no much sense to discuss details of unproven mechanism.

Maybe you can try this artcile. There you will get the perfect answer.
Dear Devidas Bhagat ,
the paper you have cited is definitely related to the title question. This is typical computational studies which ignores the acid-base distribution under experimental pH. The mechanism includes the sequence of several proton coupled electron transfers. In order to happen, each intermediate must be a dominant species at a given pH. This means that the pKa of these intermediates must be in certain narrow ranges. This is commonly ignored in such computational studies. In order to prove their mechanism, the authors had to build the Pourbaix diagram. From my point of view, this paper is very questionable.
Dear Chinnaraja Eswaran
This a very good review written by the top experts in the area, but it's relatively old. Much happened after publishing this review.
By the way, I've being a visiting professor in you Institute in the late 1980s. I was invited by Prof. Taqui Khan.and spent the unforgettable month in Bhavnagar.
Dear Yurii V Geletii
That's an awesome professor. Great to hear!!!.
