Researchers from Tokyo University use α-FeOOH, a form of rust, to improve upon hydrogen production efficiency 

March 3, 2020 |

In Japan, researchers from the Tokyo University of Science have identified a new technique that uses rust and light to speed up hydrogen production from an organic waste solution. There were three major obstacles, as described by the authors. The catalyst needed to be suitable for the use of light energy, the catalyst had to be cheaper than the notoriously expensive “noble” metals, and finally, the separation of the hydrogen and oxygen molecules needs to be done in such a way that the hydrogen production rate was not inhibited or such that resulted in an explosion. By using a form of rust called α-FeOOH, they were able to improve upon the production rate, however, the mechanism that enables this enhancement is not yet understood. Therefore understanding this method is the next intention of the researchers.
