The design of new photocatalytic systems for the generation of hydrogen from water using solar energy
In this project a novel solar cell for the generation of H2 from water will be developed. P type semiconductors will be modified with molecular components and the photocatalytic properties of these heterosupramolecular assemblies with respect to the generation of hydrogen from water will be investigated. The molecular components will consist of heterodinuclear compounds containing a light-absorbing unit connected via a bridging ligand to a catalytic centre capable of producing hydrogen. The system developed will not require sacrificial agents. Global climate change and security of energy supply are increasingly perceived as the most serious threats facing the world's medium and long-term future. The outcome expected will be a move towards an environmentally sustainable generation of hydrogen fuel. This will be of great benefit in our battle to reduce greenhouse gasses. In the Irish context the development of the environmentally friendly production methods will provide employment and the potential for exporting this technology all over the world. Further outputs will be peer reviewed articles and patents. The work outlined in this proposal will create critical mass of energy related research expertise in our laboratories.
