Metal Oxide Photoanodes for Water Splitting

2011
Solar hydrogen production through photocatalytically assisted water splitting has attracted a great deal of attention since its first discovery almost 30 years ago. The publication of investigations into the use of TiO₂ photoanodes has continued apace since and a critical review of current trends is reported herein. Recent advances in the understanding

α-Fe2O3/TiO2 stratified photoanodes

Journal of Photochemistry and Photobiology A: Chemistry, 2018
Abstract Bilayer α-Fe2O3/TiO2 thin films were prepared with the aim of minimising photocorrosion of hematite. Conductive fluorine doped tin oxide (FTO)/glass was used as substrate for successive deposition of (i) α-Fe2O3 layers by high-power impulse magnetron sputtering (HIPIMS) and (ii) TiO2 (sol-gel method using dip-coating).

Bioinspired High-Potential Porphyrin Photoanodes

The Journal of Physical Chemistry C, 2012
We report a selection of high-potential porphyrin photoanodes (HPPPs) for use in photoelectrochemical cells (PECs). The anodes consist of bispentafluorophenyl free-base and metallo-porphyrin sensitizers bearing anchoring groups for attachment to metal-oxide surfaces including TiO2 and SnO2 nanoparticles.

Photocorrosion of strontium titanate photoanodes

Solar Energy Materials, 1981
Abstract The photocorrosion of a strontium titanate photoanode was studied under acidic, neutral and alkaline conditions. It was found that in 0.5 M H2SO4, SrTiO3 corrodes very rapidly upon band-gap irradiation with an external bias. Assuming that the photocorrosion is a two-hole process releasing strontium ions, we calculated that the corrosion ...

Iron based photoanodes for solar fuel production

Physical Chemistry Chemical Physics, 2014
In natural photosynthesis, the water splitting reaction of photosystem II is the source of the electrons/reducing equivalents for the reduction of carbon dioxide to carbohydrate while oxygen is formed as the by-product. Similarly, for artificial photosynthesis where the end product is a solar fuel such as hydrogen, a water splitting-oxygen evolving ...

Nanostructured α-Fe2O3 Photoanodes

2011
Due to its abundance, stability, and ability to absorb solar irradiation, Hematite, α-Fe2O3, has been investigated for its application in solar hydrogen production via water splitting for more than three decades. However, the recent application of nanostructuring techniques has provided significant advances in the performance of hematite photoanodes ...
