Researchers from the Riken Center for Innovative Materials Science in Japan have proposed a simple and cost-effective way to store ammonia. This method will be very important scientifically and operationally.
According to Tekna technology and technology news service, ammonia is currently widely used in industries such as pharmaceuticals and textiles. It is also one of the main components in fertilizer production. Currently, to store ammonia, it is kept at a temperature of minus 33 degrees Celsius in a pressure-resistant container. In the new method, it is possible to store ammonia at lower temperatures without the need for these containers. In the new method, researchers used porous compounds of ammonia to store it at room temperature. Of course, there is a storage limitation in this method.
In their investigations, the researchers realized that perovskites, which improve the efficiency of energy conversion in solar panels with their crystal structures, will be an excellent environment for storing and recovering ammonia. The researchers found that ethylammonium lead iodide perovskite reacts with ammonia at room temperature to form lead iodide hydroxide. This material is a layered and two-dimensional structure created during the reaction with ammonia.
This substance needs only 50 degrees Celsius to recover ammonia. While porous compounds release ammonia at 150 degrees Celsius. Using this method, a way to store hydrogen can also be obtained. It is very important to detect ammonia leakage in this method. Due to the reversibility of this reaction, it can be used again to store ammonia by recovering perovskite.
