There has been a high discharge of non-biodegradable dyes into natural streams and water bodies, thus, contaminating them. Many of these dyes are synthesized by carcinogens and can be water soluble, therefore, being more problematic to remove. One effective...

Enhanced photoelectrochemical water oxidation on bismuth vanadate by electrodeposition of amorphous titanium dioxide.

Journal of the American Chemical Society

Eisenberg D, Ahn HS, Bard AJ.
PMID: 25243345
J Am Chem Soc. 2014 Oct 08;136(40):14011-4. doi: 10.1021/ja5082475. Epub 2014 Sep 26.

n-BiVO4 is a promising semiconductor material for photoelectrochemical water oxidation. Although most thin-film syntheses yield discontinuous BiVO4 layers, back reduction of photo-oxidized products on the conductive substrate has never been considered as a possible energy loss mechanism in the...

Convenient photooxidation of alcohols using dye sensitised semiconductors in combination with silver nitrate and TEMPO--an electron paramagnetic resonance study.

A new class of magnesium alloys has been developed by dissolving large amounts of oxygen atoms into a magnesium lattice (Mg-O alloys). The oxygen atoms are supplied by decomposing titanium dioxide nanoparticles in a magnesium melt at 720 °C;...

Single-Nanoparticle Collision Events: Tunneling Electron Transfer on a Titanium Dioxide Passivated n-Silicon Electrode.

Angewandte Chemie (International ed. in English)

Interfacial electron transfer at titanium dioxide (TiO2) is investigated for a series of surface bound ruthenium-polypyridyl dyes whose metal-to-ligand charge-transfer state (MLCT) energetics are tuned through chemical modification. The 12 complexes are of the form Ru(II)(bpy-A)(L)2(2+), where bpy-A is...
