Trinity College Dublin's Breakthrough: 9 Promising Catalysts for Clean Energy from Water
Scientists at Trinity College Dublin are making strides in renewable energy. They're developing a recipe for clean energy production using water as the sole waste product. Their team combines expertise in chemistry, physics, and AI to fine-tune the process.
The team's goal is to use renewable electricity to split water into hydrogen, which can be stored and used in fuel cells. The main challenge is the high energy required to break up water, particularly the 'overpotential' associated with oxygen production. Initial work showed promise and has now been significantly amplified in a recent publication in Cell Reports Physical Science.
The team aims to create a database of 80,000 'screenable' catalysts to speed up the search for the optimal combination. Using automated combinatorial approaches and quantum chemical modelling, they identified nine earth-abundant metal and ligand combinations as promising leads. These include combinations involving iron, cobalt, nickel, manganese, and copper with ligands such as bipyridine, phenanthroline, and terpyridine. Chromium, manganese, and iron are particularly promising metals for further exploration as catalysts. The team discovered that some reactive catalysts have been underestimated and refined a theoretical model to predict catalyst efficiency.
