摘要：
Electrophoretic deposition (EPD) of ground electrospun WO3 nanofibers was applied to create photoanodes with controlled morphology for the application of photoelectrochemical (PEC) water splitting. The correlations between deposition parameters and film thicknesses were investigated with theoretical models to precisely control the morphology of the nanostructured porous thin film. The photoconversion efficiency was further optimized as a function of film thickness. A maximum photoconversion efficiency of 0.924% from electrospun WO3 nanofibers that EPD deposited on a substrate was achieved at a film thickness of 18 mu m. (C) 2015 Elsevier B.V.
