“…94 In a study under elevated CO 2 pressure of 8.5 atm, the highest observed Faradaic efficiency on p-GaP was a total of 80% for HCOOH, HCHO, and CH 3 OH production, at −1.00 V vs standard Ag electrode in Na 2 CO 3 electrolyte. 95 Although nearly all of the literature studies of CO 2 reduction on p-GaP reported HCOOH, HCHO, and CH 3 OH as the products, in 1984, Ito et al claimed that formic acid was the only experimentally confirmed product of CO 2 reduction, and the rest of the organics could be ascribed to the photolysis of epoxy resin used to fabricate the cell. 96 Ito et al also suggested in a later paper that the incident light intensity strongly influences the Faradaic efficiency of HCOO − formation from CO 2 on p-GaP.…”

It is shown that illumination affects the adsorption on semiconductors, both quantitatively and qualitatively. The activity of illuminated semiconductor interfaces is studied for the particular case in which two species compete for the photogenerated charge carriers. It is concluded that, if charge transfer to only one of the species is desired, there exists an optimum level of doping of the semiconductor. The model is qualitatively illustrated by means of experimental results.) unless CC License in place (see abstract). ABSTRACTA recent theoretical treatment suggested that the impedance of fractal blocking electrodes shows fractional power frequency dependence, and the exponent is given as 1/(D -1) with D being the fractal dimension of the electrode surface.This result is now verified by a model experiment.Surface roughness has long been known to influence the frequency dispersion of the impedance of ideally polarizable (blocking) electrodes (1). Whereas blocking electrodes with a perfectly smooth surface (e.g., liquid mercury) possess purely capacitive interfacial impedance, nontrivial frequency dependence of the impedance is often observed in the case of solid electrodes with surface irregularities (2). This dispersion is a major obstacle ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
