Professor Shigeo Mori of Osaka Prefecture University and the research team of the National Institute for Materials Science have jointly developed a new catalyst to be used when decomposing water.It can be made from inexpensive and abundant resources such as iron, copper, calcium, and oxygen, and is expected to contribute to the realization of a hydrogen energy society.
The research group has succeeded in developing a new catalyst made only from iron, copper, calcium, and oxygen, which are abundant on the earth, by a method called ultra-high pressure synthesis.By preparing a sample under high pressure of tens of thousands of atmospheres, a kind of compound called perovskite can be produced.Perovskite is a substance that easily acts as a catalyst, but it has been revealed that it has a higher effect than previously known substances.Furthermore, the performance did not deteriorate even after repeated use, and it also had high durability.
The new catalyst has the advantage that the cost of materials is overwhelmingly lower than that of existing catalysts.In the future, we aim to put it into practical use by devising synthesis methods and formulations.The arrival of a hydrogen-based society has yet to be realized, but it is steadily moving toward realization.
