 Solar fuel materials

The research field of chemically driven, electrochemically driven even light-driven solar fuels, i.e. water splitting into O2 and H2 using sunlight, is expanding at an impressive rate. Dyenamo is committed to offer key materials for such applications. Dyenamo offers a selection of sensitizers, as well as water splitting catalysts for both homogeneous and heterogeneous solar fuel applications as standard materials. Other ones can be obtained on demand.
