Preparation and Characterization of Magnesium Phthalocyanine/TiO2 Nanotube Arrays Composites and Their Photodegradation for Glyphosate under Visible Light

magnesium phthalocyanine/TiO2 nanotube arrays (MgPc/TNAs) composites were prepared by electrodeposition method. The composites were characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, UV-vis diffuse reflectance spectroscopy, electrochemical impedance spectroscopy and electron spin resonance. Rhodamine B was used as the target to optimize the preparation conditions of MgPc/TNAs composites.On this basis, the photocatalytic degradation of glyphosate was studied.
