Photoelectrochemistry of metallochlorophylls

Coordination Chemistry Reviews, 1985
Abstract Photoinduced electron transfer from eleven metallochlorophyll a (MChl a) monolayers to a SnO2 substrate was investigated photoelectrochemically. Six MChl as [M = Pd(II), Cu(II), Hg(II), H2(II), Mg(II), and Zn(II)] gave measurable photoeffects. For the latter three pigments, two-dimensional dilution of the monolayer led to an enhancement of

Semiconductor photoelectrochemistry

2002
This article discusses methods and experimental protocols in semiconductor electrochemistry. We first introduce the basic principles that govern the energetics and kinetics of charge flow at a semiconductor–liquid contact. The principal electrochemical techniques of photocurrent and photovoltage measurements used to obtain important interfacial ...

Photoelectrochemistry of lithium

Journal of Power Sources, 1993
Abstract The results of investigation of the processes occurring at the lithium/nonaqueous solution interface under the influence of light irradiation are presented. The primary step of the cathodic photoeffect revealed is photoemission of electrons from lithium into passivating layers on its surface.

Photoelectrochemistry of Culn11S17

Journal of Materials Science, 1990
Polycrystalline samples of Culn11S17 have been prepared by the homogeneous precipitation technique. The electron probe microanalyses (EPMA) have shown the presence of excess sulphur with as-precipitated samples, which has been considerably reduced by subsequent annealing. From the reflectance measurements, the band gap has been determined to be 1.45eV.

Photoelectrochemistry of Polyaniline

1987
@@ This structure has recently been confirmed by a step-wise synthesis of the polymer (2). Reduction of the polymer ultimately results in the formation of the pale yellow 1eucoemeraldine oxidation state (y = 1); oxidation results ultimately in the formation of the unstable intense violet perni-graniline oxidation state (y = 0).

The photoelectrochemistry of galena

International Journal of Mineral Processing, 1994
Abstract The photoresponse of galena to chopped illumination has been studied to elucidate the surface oxidation of this mineral relevant to flotation. The results substantiated previous findings that sulfur remains in the mineral lattice during the initial stages of oxidation.
