In the photocatalysis process, the water is purified and sterilized, producing hydrogen thanks to the division of the water and this can be used to generate electricity. For the process, only titanium is required as a catalyst and sunlight, but the production of hydrogen is low, which is solved with the addition of reducing agents, a function that some organic pollutants perform very well.

By combining the two mechanisms, energy production performance can be improved and the cost of generating hydrogen can be reduced while water purification is achieved efficiently. Similar methods have been proposed but require external power supplies so they cannot be used in remote locations.
