Novel 3D urchin-like TiO2 microstructures decorated with Ag nanoparticles were successfully fabricated by one-step solvothermal method with the mixed solution of ethylene glycol, AgNO3 and tetrabutyl titanate. The morphology, microstructure, crystalline and composition of the composite materials could be adjusted through changing the content of AgNO3, solvothermal temperature and time. The obtained samples were characterized by TEM, XRD and XPS. The formation mechanism of these microstructures was proposed. The Ag nanoparticle-decorated 3D urchin-like TiO2 microstructures showed excellent photocatalytic activity for the degradation of Rhodamine B under UV-Vis irradiation, which was attributed to their special 3D superstructure, crystalline composition and Ag nanoparticle decorated as well.
