A new catalyst utilizing single atoms of platinum, developed by City University Hong Kong and tested by Imperial College London, promises easier and cost-effective hydrogen storage from renewable energy. The innovation disperses platinum atoms on molybdenum sulphide, reducing platinum usage and improving electrolysis efficiency.
Renewable energy generation, from sources like wind and solar, is rapidly growing. However, some of the energy generated needs to be stored for when weather conditions are unfavorable for wind and sun. One promising way to do this is to save energy in the form of hydrogen, which can be stored and transported for later use.To do this, the renewable energy is used to split water molecules into hydrogen and oxygen, with the energy stored in the hydrogen atoms.
Growing the thin catalysts on nanosheet supports allowed the CityU team to create high-purity materials. These were then characterized in Professor Kucernak’ lab at Imperial, which has developed methods and models for determining how the catalyst operates.
