Ag-Functionalized CuWO4/WO3 nanocomposites for solar water splitting
Abstract
<p>Ag-Functionalized CuWO<sub>4</sub>/WO<sub>3</sub> heterostructures were successfully prepared via a polyvinyl pyrrolidone (PVP)-assisted sol-gel (PSG) route. Thin films prepared via electrophoretic deposition were used as photoanodes for photoelectrochemical (PEC) water splitting. Compared to pristine CuWO<sub>4</sub> and WO<sub>3</sub> films, a significant enhancement of the photocurrent (3-4 times) at the thermodynamic potential for oxygen evolution (0.62 V vs. Ag/AgCl, pH 7) was obtained for the Ag-functionalized CuWO<sub>4</sub>/WO<sub>3</sub> photoanodes. The obtained enhancement is shown to be derived from a synergic contribution of heterostructure formation (CuWO<sub>4</sub>/WO<sub>3</sub>) and improvements of light utilization by Ag-induced surface plasmon resonance (SPR) effects. Accordingly, a photocurrent of 0.205 mA cm<sup>-2</sup> at 0.62 V vs. Ag/AgCl under neutral conditions (without hole scavengers) under front-side simulated AM1.5G illumination was achieved. A detailed analysis of the obtained PEC data alongside performed impedance measurements suggests that charge seperation is significantly improved for the prepared Ag-functionalized CuWO<sub>4</sub>/WO<sub>3</sub> photoanodes. Our work offers beneficial insights to design new plasmonic metal/heterostructured nanocomposites for energy conversion applications.</p>
