Molecular Metal-Oxo Catalysts for Generating Hydrogen from Water (2724)
This invention is a new type of catalyst that can produce hydrogen from water, even in untreated seawater, using a molecular metal-oxo complex that has a longer lifetime and higher turnover frequency than previous electrocatalysts. The catalyst is cost-effective and can be fine-tuned by modifying its ligand platform and metal center, and could potentially replace fossil fuels in various transportation applications.
