Journal ArticleDOI
Stabilization of n-cadmium telluride photoanodes for water oxidation to O2(g) in aqueous alkaline electrolytes using amorphous TiO2 films formed by atomic-layer deposition
Michael F. Lichterman,Azhar I. Carim,Matthew T. McDowell,Shu Hu,Harry B. Gray,Bruce S. Brunschwig,Nathan S. Lewis +6 more
TL;DR: In this article, an n-CdTe/TiO2/Ni oxide electrode with a thin overlayer of a Ni-oxide based oxygen-evolution electrocatalyst was shown to achieve stable solar-driven photoelectrochemical oxidation of H2O to O2(g).
Journal ArticleDOI
Optical, electrical, and solar energy-conversion properties of gallium arsenide nanowire-array photoanodes
Shu Hu,Chun-Yung Chi,Katherine T. Fountaine,Maoqing Yao,Harry A. Atwater,P. Daniel Dapkus,Nathan S. Lewis,Chongwu Zhou +7 more
TL;DR: In this paper, the optical absorption characteristics of the nanowire-arrays were investigated experimentally and theoretically, and the photoelectrochemical energy-conversion properties of GaAs nanowires were evaluated in contact with one-electron, reversible, redox species in nonaqueous solvents.
Journal ArticleDOI
Amorphous TiO2 Coatings Stabilize Si, GaAs, and GaP Photoanodes for Efficient Water Oxidation.
Shu Hu,Matthew R. Shaner,Joseph A. Beardslee,Michael F. Lichterman,Bruce S. Brunschwig,Nathan S. Lewis +5 more
TL;DR: In this paper, the authors describe the deposition of thin overlayers of TiO2 (4-143 nm) on Si, GaAs, and GaP electrodes by atomic layer deposition.
Journal ArticleDOI
Preparation and Electrochemical Characterization of Conical and Hemispherical Ultramicroelectrodes
TL;DR: In this paper, a new ultramicroelectrode fabrication technique has been described, which has allowed the preparation of conical and hemispherical platinum-iridium ultramer with radii of 0.5 micro m-10 micro m. These electrodes have been characterized by scanning electron microscopy, cyclic voltammetry and chronoamperometry.
Journal ArticleDOI
Highly Sensitive Detection and Discrimination of Biogenic Amines Utilizing Arrays of Polyaniline/Carbon Black Composite Vapor Detectors
TL;DR: In this paper, chemical-sensitive resistors have been developed that allow rapid detection of an important class of compounds, biogenic amines, at levels of 1−10 parts per trillion in ambient air.
