PHOTOANODIC ENGRAVING OF HOLOGRAMS ON SILICON
Applied Physics Letters, 1970Holograms have been recorded on the surface of Si by means of a photoanodic reaction. Resolution better than 2500 lines/mm have been achieved in holographically recorded gratings. Diffuse object holograms with reconstruction efficiencies as high as 10% have also been obtained.

Metal Oxide Photoanodes for Water Splitting
2011Solar 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

Photocorrosion of strontium titanate photoanodes
Solar Energy Materials, 1981Abstract 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 ...

The photoelectrochemical properties of Sn2Nb2O7 photoanode
Journal of Alloys and Compounds, 2019Abstract Sn2Nb2O7 photoanode has been fabricated by the electrophoretic deposition method and its photoelectrochemical (PEC) properties were studied carefully. The energy band structure of Sn2Nb2O7 was analyzed by Mott-Schottky plots, the results show that its energy band structure matches the requirement of PEC water splitting, the low absolute ...

Iron based photoanodes for solar fuel production
Physical Chemistry Chemical Physics, 2014In 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 ...

On the orbital anisotropy in hematite nanorod-based photoanodes
Physical Chemistry Chemical Physics, 2013The orbital anisotropy of hematite (α-Fe2O3) nanorod arrays, an engineered structure commonly investigated for applications in solar water oxidation photoanodes, is probed using polarization-dependent soft X-ray absorption spectroscopy at the O K-edge and at the Fe L2,3-edge. Thereby the unoccupied states of α-Fe2O3 are examined.

Photoelectrochemical Activity of Sodium Titanate Nanobelts for Photoanode
Journal of Nanoscience and Nanotechnology, 2015We report photoelectrochemical characteristics of sodium titanate nanobelts as a photoanode. Sodium titanate nanobelts were synthesized by hydrothermal process using titanium(IV) tetrabutoxide in a concentrated aqueous NaOH solution. The formation mechanism of sodium titanate nanobelts in the synthetic process has been comparatively studied on the ...
