Sn(IV)porphyrin-Anchored TiO<sub>2</sub> Nanoparticles via Axial-Ligand Coordination for Enhancement of Visible Light-Activated Photocatalytic Degradation
A visible-light-active photocatalyst, SnP/AA@TiO<sub>2</sub>, was fabricated by utilizing the coordination chemistry between the axial hydroxo-ligand in the (<i>trans</i>-dihydroxo)(5,10,15,20-tetraphenylporphyrinato)Sn(IV) complex (SnP) and adipic acid (AA) on the surface of...

| description | A visible-light-active photocatalyst, SnP/AA@TiO<sub>2</sub>, was fabricated by utilizing the coordination chemistry between the axial hydroxo-ligand in the (<i>trans</i>-dihydroxo)(5,10,15,20-tetraphenylporphyrinato)Sn(IV) complex (SnP) and adipic acid (AA) on the surface of TiO<sub>2</sub> nanoparticles. The SnP center was strongly bonded to the surface of the TiO<sub>2</sub> nanoparticles via the adipic acid linkage in SnP/AA@TiO<sub>2</sub>, as confirmed by various instrumental techniques. SnP/AA@TiO<sub>2</sub> exhibited remarkably enhanced photocatalytic activity toward the degradation of rhodamine B dye (RhB) in aqueous solution under visible-light irradiation. The RhB degradation efficiency of SnP/AA@TiO<sub>2</sub> was 95% within 80 min, with a rate constant of 0.0366 min<sup>−1</sup>. The high degradation efficiency, low catalyst loading and high reusability make SnP-anchored photocatalysts more efficient than other photocatalysts, such as TiO<sub>2</sub> and SnP@TiO<sub>2</sub>. |
