Scientists at the Japanese research institute RIKEN have found a compound designed to carry ammonia with hydrogen. The results of the research were published by the journal. Journal of the American Chemical Society (JACS).
Hydrogen is considered an alternative energy source, but it is difficult to store and transport due to its flammability. Ammonia (NH3) is often used as a carrier molecule. It is stored by liquefaction at temperatures well below freezing in pressure-resistant containers.
To simplify the storage of ammonia, the researchers proposed using the perovskite EAPbI3, a mineral with a crystalline structure corresponding to the formula ABX3. A slightly broken cube. This structure allows the inclusion of various cations (positively charged ions), which makes it possible to create materials with various useful properties.
Scientists have found that perovskite greatly simplifies the storage of ammonia and also allows its complete removal at a relatively low temperature. It has a one-dimensional columnar structure that chemically reacts with ammonia causing the latter to deposit in the perovskite. Experts have found that this method of storing ammonia is much cheaper than liquefying.
Former scientists in Germany created a substance that, like plants, splits water into oxygen and hydrogen.
