Advanced semiconductors for photo-electrocatalytic solar fuel production
Universitat Jaume I (2020-07-20)Uno de los retos actuales de la ciencia y la tecnología es el desarrollo y utilización de fuentes de energías limpias, sostenibles y seguras, con el fin de sustituir el uso de combustibles fósiles. La energía solar, única ... -
Carrier density and interfacial kinetics of mesoporous TiO2 in aqueous electrolyte determined by impedance spectroscopy
Elsevier (2012)Water splitting at a semiconductor/solution interface with the only input of sunlight to generate hydrogen is one of the most attractive strategies to produce and store chemical energy. In the present study we have ... -
Interpretation of cyclic voltammetry measurements of thin semiconductor films for solar fuel applications
American Chemical Society (2013)A simple model is proposed that allows interpretation of the cyclic voltammetry diagrams obtained experimentally for photoactive semiconductors with surface states or catalysts used for fuel production from sunlight. When ... -
Plasmonic versus catalytic effect of gold nanoparticles on mesoporous TiO2 electrodes for water splitting
Elsevier (2014-10)Solar water splitting with metal oxide semiconductors constitutes a promising approach to the conversion of solar energy into chemical energy stored in the atomic bonds of hydrogen molecules. In the present study, we ... -
Understanding the Role of Underlayers and Overlayers in Thin Film Hematite Photoanodes
Wiley (2014-12-23)Recent research on photoanodes for photoelectrochemical water splitting has introduced the concept of under- and overlayers for the activation of ultrathin hematite films. Their effects on the photocatalytic behavior were ... -
Water oxidation at hematite photoelectrodes: the role of surface states
American Chemical Society (2012)Hematite (α-Fe2O3) constitutes one of the most promising semiconductor materials for the conversion of sunlight into chemical fuels by water splitting. Its inherent drawbacks related to the long penetration depth of light ...
