Composition and photoelectrochemical properties of WO3/TNAs photoelectrodes fabricated by in situ electrochemical method
چکیده انگلیسی
TiO2/Ti Nanotube arrays (TNAs) and WO3/TNAs photoelectrodes were fabricated by in situ anodization and cycle pulse electrochemical deposition method. The morphology and structure were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectra and X-ray photoelectron spectroscopy (XPS). Optical properties and photoelectrochemical (PECH) properties were investigated by surface photovoltage (SPV), ultra UV-vis diffuse reflectance spectra (UV/vis/DRS), open-circuit potential (OCP), and photocurrent density The results showed that WO3/TNAs photoelectrodes have excellent photoresponse performance. WO3 would enhance the photovoltage and photocurrent of TNAs photoelectrodes. The presence of WO3 caused red shift and enhanced the photosensitivity of TNAs photoelectrodes in whole light region.
