SYNTHESIS AND CHARACTERIZATION OF [IrL3]3+/ZEOLITE Y ASSEMBLIES FROM INDIGENOUS MINERAL SOURCES AND ITS APPLICATION IN PHOTOCATALYSIS (original) (raw)

Abstract

“Ship in a bottle” assemblies of Iridium complexes encapsulated in zeolite Y cages will be synthesized via a two-step process. These composites will then be tested for their electron transfer property and photocatalytic function when doped with TiO2. Rhodamine B will be employed as a model pollutant and its kinetics of degradation will be monitored via UV-Vis spectrophotometry. Characterization of the synthesized [IrL3]3+/Zeolite Y composites will be done using IR spectroscopy, UV-Vis spectroscopy and SEM-EDX. The absorption and emission spectrum of the [IrL3]3+/Zeolite Y composite both in the solid state and the diffused-state will be evaluated to assess its compatibility with TiO2 in a photocatalytic system. Differential pulse voltammograms of the assembled composite will be used to confirm the encapsulation the Iridium complexes inside the zeolite Y super cages. Molecular modelling and computational methods may also be employed for the assessment of the “ship in a bottle” structu...
