TiO2 photoanodes for electrically enhanced water splitting
International Journal of Hydrogen Energy, 2010Photoelectrochemical properties of self-organized TiO2 nanotubes formed by electrochemical anodization of titanium sheets and their working mechanism are investigated. Formation and growth of self-organized nanotubes were carried out by Titanium anodization in acid electrolyte containing fluorides.

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.

Optimizing charge extraction in oxynitride photoanodes
2021Our dependency on fossil fuels remains the largest contributing factor to anthropogenic climate change. One potential solution to our energy supply problem could be to harness our largest source of renewable energy – our sun – in the form of the solar fuel.

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 ...

Hemisquaraine Dye Performance on Different Photoanodes
2013We have recently proposed a new metal-free organic dye, CT1, based on a simple hemisquaraine molecule. The CT1 dye is prepared following an easy and inexpensive three steps synthesis: quaternarization, coupling and hydrolysis, according to a classical procedure for hemisquaraine dyes.

Studies on polycrystalline cadmium sulphide photoanodes
Journal of Power Sources, 1988The spectral dependence of absolute quantum efficiency for chemically deposited cadmium sulphide thin-film electrodes in 1 M NaOH: 0.1 M Na2S:0.1 M S, is reported. A peak quantum efficiency of 1.75 × 10−2 is observed at λ = 560 nm. The diffusion length of minority carriers has been calculated from Gartner's photocurrent equation.

Interfacial Phenomena of Some Titanate Photoanodes
Berichte der Bunsengesellschaft für physikalische Chemie, 1984AbstractTwo types of titanate photoanodes are discussed, viz. mechanically polished n‐TiO2: Nb and hydrogen‐reduced n‐SrTiO3: Nb surface‐doped with LaCrO3. The anodes are investigated in acidic as well as in basic solutions. In addition the influence of ultraviolet irradiation is examined.

(Invited) Artificial Photosynthesis Using Plasmonic Photoanode
ECS Meeting Abstracts, 2018Previously, we have demonstrated plasmonic photocurrent generation from visible to near-infrared wavelengths without deteriorating photoelectric conversion using photoanodes in which gold nanorods were elaborately arrayed on the surface of a TiO2 single crystal [1-3].
