英文摘要: Abstract(#br)A kind of novel heterojunction structure with black TiO 2 and WS 2 was prepared with matched energy band and significantly improved visible-light-driven photoelectrochemical activity. Then, to further improve the photoelectrochemical activity of this heterojunction, solid-state electron donor of polydopamine was employed with satisfactory result. The band gap, potential of conduction band and valence band was investigated using Mott-Schottky curve, VB-XPS and UV–vis diffuser reflectance techniques. These materials were also characterized by SEM, TEM, XRD, IR, Roman spectra, and EPR image. The improved photoactivity was confirmed by monitoring and comparing the photocurrent response of black TiO 2 , WS 2 and Black TiO 2 /WS 2 heterojunction. To explore the applicability of...
