摘要
Advanced multifunctional sponge-type materials are obtained following chemical treatment of a Visible Light Photocatalyst (VLP) with an alkali aqueous solution under selected conditions. The resulting multifunctional material is fully characterized by XRD, SEM/EDX, TEM, FT-IR, RAMAN, and UV-Vis. It is found that the resulting material has high affinity to cationic dyes such as methylene blue (MB) and rhodamine 6G (Rh6G) and, thus may be employed as an environmental selective adsorbant for industrial wastewaters consisted of different mixtures of anionic and cationic dyes. On the other hand, this sponge like material if activated under visible light irradiation exhibits high photocatalytic activity for the decomposition of methylene blue in a solid state.
