"Ship-in-a-Bottle” Synthesis of Fluorescent Iridium (III) Complex Ion unto Zeolite Y Supercages

Abstract:

Incorporation of photosensitizer complex, Ir (bpy)₃³⁺ inside zeolite Y supercages was done via “ship-in-a-bottle” synthesis method. Elemental analysis of the Ir (III) exchanged – zeolite Y showed that the ratio of Ir to Al to Si (Ir:Al:Si) was 1:1.6:2. The light-harvesting ability of the iridium complex has been observed in the absorption spectra of the composite. Grafting the surface of the zeolite with TiO₂ was done to assess the possibility of electron injection from the complex to a photocatalytic surface. Results of the degradation study using Ir (bpy)₃³⁺/zeolite Y/TiO₂ assembly resulted in a two-fold increase in the rate of degradation of RhB as compared to the TiO₂ alone. This paper demonstrates the potential application of Ir (III) dyes entrapped inside a zeolite matrix for the construction of photocatalytic assemblies.
