Generally the water has been decomposed into oxygen and hydrogen in the presence of electrical power.
Can this action occures without electrical power ? for example under the action of a catalyst only ?
Hello Qian Xu
Thank you for your answer...
What a kind of catalyst could be used in this case?
If you learn basics of thermodynamics you will never ask such questions. A catalyst does not change the reaction thermodynamics
Dear Dr. Sellami Mohamed Hassen
Photocatalytic hydrogen production through splitting of water is a process that converts solar energy into chemical energy by means of a suitable photocatalyst. For this purpose, one can use different catalysts such as TiO2 and ZnO-based photocatalysts. Although this reaction thermodynamically is unspontaneous, the applied light provides energy for this reaction. In electrical splitting of water, electricity provides energy for this conversion. These thermodynamically unspontaneous reactions are very similar to photosynthesis reactions in plants, in which CO2 molecules converts to organic compounds. In addition, by using photocatalytic processes, one can convert CO2 gas to value-added fuels such as methanol. This is an unspontaneous reaction also. For more information, please refer to the attached review papers.
Hello Aziz
Thank you very much for the three review papers...
Regards.
