The oxygen evolution reaction (OER) is the key reaction to enable the storage of solar energy in the form of hydrogen fuel through water splitting. Efficient, Earth-abundant, and robust OER catalysts are required for a large-scale and cost-effective production of solar hydrogen. While OER catalysts based on metal oxides exhibit promising activity and stability, their rational design and developments are challenging due to the heterogeneous nature of the catalysts. The overall objectives of the project is to (i) understand OER on metal oxides at the molecular level and engineer catalytic sites at the atomic scale; (ii) develop and apply practical OER catalysts for high-efficiency water splitting in electrochemical and photoelectrochemical devices.
We have worked on the development of new synthetic methods for OER catalysts, the design and development of new catalysts, the characterization of catalysts at a molecular level including the development of new tools, and the integration of catalysts into light-harvesting devices. We have obtained significant results: (1) Several novel synthetic methods have been developed; (2) Several novel classed of efficient OER catalysts have been developed; (3) An in-situ Raman spectroscopic tool has been set up; (4) Unprecedented direct spectroscopic data on the active sites of catalysts have been obtained; (5) An efficient photo device incorporating an OER catalyst has been constructed.
(1) In-situ and operando characterization of well-defined solid-state catalysts by spectroscopy, microscopy, and combination of both.
(2) Measurement of active sites of solid-state catalysts by using well-defined novel catalysts developed in the project.
(3) New design principles for next generation high performing catalysts based on comprehensive molecular level mechanistic studies.
