Semiconductor Electrodes: X . Photoelectrochemical Behavior of Several Polycrystalline Metal Oxide Electrodes in Aqueous Solutions
Abstract
An investigation was made of the photoelectrochemical properties of several polycrystalline metal oxide electrodes prepared by chemical vapor deposition, direct oxidation of the metal or heating of suitable metal salt solutions. Further data are given on the behavior of the previously discussed TiO/sub 2/ and Fe/sub 2/O/sub 3/ electrodes including tunneling effects and the operation of the Fe/sub 2/O/sub 3/ in a solar cell. Other n-type materials studied were V/sub 2/O/sub 5/, WO/sub 3/, and PbO. WO/sub 3/ and PbO showed good anodic photocurrents but only WO/sub 3/ appeared stable. Bi/sub 2/O/sub 3/ showed both n- and p-type photocurrents, but had a poor stability. CuO produced a good cathodic photocurrent (indicating p-type behavior) with a photoresponse at wavelengths of 700 nm and below. Two other oxides, Cr/sub 2/O/sub 3/ and CoO, exhibited small p-type photoeffects.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
