High-Throughput Characterization of Structural and Photoelectrochemical Properties of a Bi–Mo–W–O Thin-Film Materials Library
Abstract
<jats:title>Abstract</jats:title> <jats:p>A Bi–W–Mo–O thin-film materials library was fabricated by combinatorial reactive magnetron sputtering. The composition spread was investigated using high-throughput methods to determine crystalline phases, composition, morphology, optical properties, and photoelectrochemical performance. The aurivillius phase (Bi<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>)<jats:sup>2+</jats:sup> (Bi<jats:sub>M</jats:sub>(W<jats:sub>1−N</jats:sub>Mo<jats:sub>N</jats:sub>)<jats:sub>M−1</jats:sub>O<jats:sub>3M+1</jats:sub>)<jats:sup>2−</jats:sup> is the predominantly observed crystal structure, indicating that the thin films in the library are solid solutions. With increasing amounts of Mo ≙ 7–22% the diffraction peak at 2θ = 28° ≙ [131] shifts due to lattice distortion, the photoelectrochemical activity is increasing up to a wavelength of 460 nm with an incident photon to current efficiency (IPCE) of 4.5%, and the bandgap decreases. A maximum photocurrent density of 31 μA/cm<jats:sup>2</jats:sup> was measured for Bi<jats:sub>31</jats:sub>W<jats:sub>62</jats:sub>Mo<jats:sub>7</jats:sub>O<jats:sub>z</jats:sub> at a bias potential of 1.23 V vs. RHE (0.1 M Na<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub>).</jats:p>
