Prof. Leticia Torres-Martínez research leadership is distinguished for developing new materials (in powder and thin films) with semiconductor properties that present a favorable combination of electronic structure and property of absorbing light, in addition to efficiently absorbing reagents, to achieve high efficiencies of photo(electro)catalysts in a) H2O conversion, b) CO2 photoconversion, and c) the degradation of organics in water. Her work's scientific and technical novelty involves developing and coupling advanced photocatalysts for their use in photoinduced processes to obtain alternative clean and renewable energy sources. Different innovative strategies were implemented, such as the deposition of earth-abundant cocatalysts, the formation of heterostructures, and the preparation of highly faceted nanostructures films by laser CVD. All these strategies are employed to increase the charge carriers' lifetime, promote the separation of the charges in the interface, and increase the photo(electro)catalytic efficiency. Also, she has led the investigations of two families of materials with the highest efficiencies in the photocatalytic production of hydrogen, in orders of up to 20 times greater than those reported in indexed journals by other international research groups.
