TiO(2) bilayer films with a normal surface (Ns-TiO(2)), surface defects (Sd-TiO(2)), and interface defects (Id-TiO(2)) were successfully prepared by a combination of cold plasma treatment (CPT) and sol-gel dip-coating technology. The photodegradation of rhodamine B (RhB) over these as-prepared TiO(2) films was investigated via UV-vis irradiation. Results indicate that the three kinds of films exhibit very different photodegradation processes for RhB. A mainly N-deethylation reaction over the Ns… CONTINUE READING
