Recent Advances in Visible-Light-Driven Photoelectrochemical Water Splitting: Catalyst Nanostructures and Reaction Systems
Photoelectrochemical (PEC) water splitting using solar energy has attracted great attention for generation of renewable hydrogen with less carbon footprint, while there are enormous challenges that still remain for improving solar energy water splitting efficiency, due to limited light harvesting, energy loss associated to fast recombination of photogenerated charge carriers, as well as electro...
متن کاملVisible Light Driven Photoelectrochemical Water Splitting on Metal Free Nanoporous Carbon Promoted by Chromophoric Functional Groups
A nanoporous carbon was prepared from sulfonic acid based water soluble polymer. Its direct one step carbonization followed by air oxidation led to a porous material whose surface was rich in N-, Oand Scontaining groups. TEM images showed the presence of 10 nm graphitic domains in the carbon matrix. When the carbon was used as a photoanode under visible light irradiation, oxygen evolution occur...
متن کاملA photoelectrochemical device for visible light driven water splitting by a molecular ruthenium catalyst assembled on dye-sensitized nanostructured TiO2.
A photoelectrochemical device with a molecular Ru catalyst assembled via pH-modified Nafion on a dye-sensitized nanostructured TiO(2) film as anode and a Pt foil as cathode has been successfully demonstrated to split water into O(2) and H(2) driven by visible light.
متن کاملSelf-biasing photoelectrochemical cell for spontaneous overall water splitting under visible-light illumination.
A self-biasing photoelectrochemical (PEC) cell that could work for spontaneous overall water splitting in a neutral solution was established based on the mismatched Fermi levels between the photoelectrodes. A Pt-catalyst-decorated crystalline silicon photovoltaic cell (Pt/PVC) was prepared and employed as an effective photocathode. This was coupled with a poly(ethylene glycol)-directed WO3/W ph...
متن کاملPhotoassisted overall water splitting in a visible light-absorbing dye-sensitized photoelectrochemical cell.
Iridium oxide nanoparticles stabilized by a heteroleptic ruthenium tris(bipyridyl) dye were used as sensitizers in photoelectrochemical cells consisting of a nanocrystalline anatase anode and a Pt cathode. The dye coordinated the IrO(2) x nH(2)O nanoparticles through a malonate group and the porous TiO(2) electrode through phosphonate groups. Under visible illumination (lambda > 410 nm) in pH 5...
