Researchers led by Genki Kobayashi at the RIKEN Pioneering Research Institute (PRI) in Japan recently discovered a way to max out the amount of hydrogen that can be stored in perovskite crystalline powder. The trick is to introduce the hydrogen into the perovskite lattice structure using mechanochemistry – chemical reactions that occur by physically grinding and mixing compounds together. This process also affects the crystalline structure of the powder, making it an even better catalyst for...
