Abstract
Silver-modified 3D singlecrystal nanowires-assembled rutile TiO2 nanoflowers (SMTNs) have been synthesized via a facile surfactant-assisted hydrothermal and followed by photo-reduction Ag-loading method, in which controlled hydrolysis of titanium isopropoxide (TTIP) in a mixed solution of hydrochloric acid (HCl) and cetyltrimethyl ammonium bromide (CTAB) with using AgNO3 as silver source. The physical and chemical properties of SMTNs were studied by XRD, FESEM, HRTEM and UV–vis diffuse reflectance spectra (DRS) techniques. The photocatalytic activity of the SMTNs was evaluated by photocatalytic degradation of Rhodamine B (Rh B) aqueous solution under visible light irradiation. The experimental results showed that the SMTNs exhibited a much better photocatalytic activity than that of TNs (TiO2 nanoflowers) and P25 (commercial TiO2).
