Abstract
The composite TiO2 nanotube arrays/5,10,15,20-tetrakis(4-chlorophenyl) porphyrin (H2TClPP-TNTs) photoelectrode with high visible light photoelectrochemical properties was prepared by a facile surface adsorption method. The morphology, composition and optical property of H2TClPP-TNTs photoelectrode was investigated by scanning electron microscopy, X-ray diffraction, FT-IR spectra, X-ray photoelectron spectroscopy and UV-vis diffuse reflectance spectroscopy. The sensitization of H2TClPP on TNTs significantly extended the visible light response, the as-prepared H2TClPP-TNTs photoelectrode exhibits excellent photoelectrochemical performance and photocatalytic activity. The photodegradation efficiency of rhodamine B by using H2TClPP-TNTs irradiated under visible light for 4Â h was up to 92.8%, which was higher than that of pure TiO2 nanotube arrays.
