We do water oxidation experiments to generating H2 as a carbon free fuel from water and the main purpose is that we want to use this process for turning the solar energy to a storable chemical fuel. Hence this chemical reaction type is not useful for the above purpose. what are benefits of chemical water oxidation except determination of catalyst's TON or TOF or maybe use of this reaction to generate fuel in places that they don't have enough sun's radiation? Why we are still doing chemical water oxidation experiments beside photochemical, photoelecterochemical and electro chemical water oxidation experiments that matches to our purpose?
Dear Sina Safavi, oxidation and oxidants are used for water purification. My Regards
Dear Abdelkader BOUAZIZ
Your answer is not related to my question. I'm asking about chemical water splitting reaction and chemical water oxidation half reaction not the role of oxidant in water purification. the attached file will help you to perceive what I am asking about.
water splitting reaction: 2 H2O --> 2 H2 + O2
water oxidation half reaction: 2 H2O --> O2 + 4 H+ + 4e-
I know about this stuff, just I want to extended a meaning that related to oxidation in water. Water splitting is supposed to be the future green alternative to fossil sources of energy. Many processes are in continuous développement mainly those based on natural radiation. My Regards
Abdelkader BOUAZIZ It is not an answer to my question but thank you any way.
Yes it is not an answer, I just clarified the reason behind my first contribution. No the following information I add are supposed to be know for you. - Metal oxides nanoparticles such as TiO2 are replacing replacing precious metals in photocatalytic water splitting. The economical feasability of most water splitting processes still not benificial. There are many things to deal with, for that please take a look at the following documents. My Regards

The main benefit is the simplicity of such systems. Unfortunately, only several oxidants can do water oxidation.
Finally a related and useful answer to my question. Thanks a lot dear Yurii V Geletii
Hello everyone,
How to perform the water oxidation reaction in a microbial fuel cell ? Which is the best electrode material for performing water oxidation?
