Stability and self-passivation of copper vanadate photoanodes under chemical, electrochemical, and photoelectrochemical operation.
Deployment of solar fuels technology requires photoanodes with long term stability, which can be accomplished using light absorbers that self-passivate under operational conditions. Several copper vanadates have been recently reported as promising photoanode materials, and their stability and self-passivation is demonstrated through a combination of Pourbaix calculations and combinatorial exper...
متن کاملReactive Sputtering of Bismuth Vanadate Photoanodes for Solar Water Splitting
Bismuth vanadate (BiVO4) has attracted increasing attention as a photoanode for photoelectrochemical (PEC) water splitting. It has a band gap in the visible light range (2.4−2.5 eV) and a valence band position suitable for driving water oxidation under illumination. While a number of methods have been used to make BiVO4 photoanodes, scalable thin film deposition has remained relatively underexp...
متن کاملSimultaneous enhancements in photon absorption and charge transport of bismuth vanadate photoanodes for solar water splitting
n-Type bismuth vanadate has been identified as one of the most promising photoanodes for use in a water-splitting photoelectrochemical cell. The major limitation of BiVO4 is its relatively wide bandgap (∼2.5 eV), which fundamentally limits its solar-to-hydrogen conversion efficiency. Here we show that annealing nanoporous bismuth vanadate electrodes at 350 °C under nitrogen flow can result in n...
متن کاملMechanistic insights into chemical and photochemical transformations of bismuth vanadate photoanodes
Artificial photosynthesis relies on the availability of semiconductors that are chemically stable and can efficiently capture solar energy. Although metal oxide semiconductors have been investigated for their promise to resist oxidative attack, materials in this class can suffer from chemical and photochemical instability. Here we present a methodology for evaluating corrosion mechanisms and ap...
متن کاملImproved charge separation via Fe-doping of copper tungstate photoanodes.
Photoelectrochemical (PEC) water splitting offers a clean pathway to renewable and sustainable energy in the near future. The key to improving the efficiency of PEC devices is the ability to find materials with suitable optoelectronic properties, and identifying, then overcoming their limitations. In this paper, we explore the photoelectrochemical performance of CuWO4 photoanodes for solar wate...
