Nesting BiVO<sub>4</sub> nanoislands in ZnO nanodendrites by two-step electrodeposition for efficient solar water splitting
Abstract
<jats:title>Abstract</jats:title><jats:p>Photoanodes with a large electrochemically active surface area, rapid charge transfer, and broadband light harvesting capacity are required to maximize the photoelectrochemical (PEC) water splitting performance. To address these features, we demonstrate that 3D hierarchal ZnO nanodendrites (NDs) can be sensitized with BiVO<jats:sub>4</jats:sub> nanoislands by chemical and thermal treatments of electrodeposited Bi metal films. The flat band measurements and optical characterization suggested that the resulting heterojunction had type-II band alignment with a viable charge transfer from BiVO<jats:sub>4</jats:sub> to ZnO NDs. In parallel, PL analysis revealed inhibition of the charge recombination rate by the electron transfer between BiVO<jats:sub>4</jats:sub> and ZnO NDs. Upon AM 1.5 G illumination, BiVO<jats:sub>4</jats:sub>/ZnO NDs heterojunction yielded the highest photocurrent efficiency (0.15 mA·cm<jats:sup>−2</jats:sup> at 1.2 V vs. NHE), which was attributed to its enhanced surface area (due to the presence of small dendrite branches), extended broadband light absorption extending from UV to visible light regions, and the most efficient interfacial charge transfer as proven by electrochemical impedance spectroscopy (EIS) studies. Besides, the incident photon-to-current conversion efficiency and applied bias photon-to-current efficiency tests confirmed an improved spectral photoresponse of the heterojunction based photoanode, particularly towards the visible light spectrum. The results outline a promising synthesis route for building heterojunctions between visible light active and wide band gap semiconductors for the use as a highly efficient photoanodes in a PEC cell.</jats:p>
