Chemically derivatized semiconductor photoelectrodes

Abstract

The aim of this article is to highlight the significant results from a modification of a photoelectrode surfaces. From State-of-the-Art Symposium: Electrochemistry, ACS meeting, Kansas City, 1982.

Electron transfer at semiconductor electrode-liquid electrolyte interfaces

“…This type of system received considerable attention in the early 1980s because it resulted in lower corrosion rates in some systems. 26 Strategies for surface bonding of molecules to surfaces has been extensively reviewed; the review by Murray contains a specific discussion of the modification of semiconductor surfaces.91…”

Efficient Light-to-Electrical Energy Conversion: Nanocrystalline TiO2 Films Modified with Inorganic Sensitizers

“…The use of solid state materials for efficient conversion of sunlight into electricity has long been a goal of inorganic photochemistry (1,2). A molecular approach has been to sensitize wide-bandgap semiconductors to visible light with inorganic compounds exhibiting charge-transfer excited states.…”

Photooxidation of Water with Thin Film Tungsten Oxides

“…Fujishima and Honda were photoelectrochemical pioneers in the early 1970s, using wide band gap, n-type TiO 2 to split water, while Hodes et al introduced WO 3 a few years later. This Journal documented the early advances in PECs for the direct conversion of sunlight into chemical fuels such as hydrogen, − while recent reports address the electrochemistry of semiconductor-assisted photooxidation , and the catalysis of water photooxidation. − All of this work is grounded in a firm understanding of electrocatalysis in water splitting, the insights provided by electrochemical techniques, the energetics of photochemical reactions, and an understanding of photo quantum yield …”
