Abstract

The photochemical activation and reduction of CO2 over a molecular-sieve-encapsulated rhenium complex was investigated under photoirradiation (lambda> 350 nm) at room temperature. Re(CO)(3)(bpy)Cl and [Re(CO)(3)(bpy)(py)](+) were respectively encapsulated in the microporous NaY and the mesoporous AlMCM-41 molecular sieve acting as supramolecular heterogeneous host. The molecular-sieve-encapsulated rhenium complexes were characterized by diffusereflectance(DR) ultraviolet-visible (UV-vis), photoluminescence, and Fourier transform infrared (FTIR) spectroscopy. The interaction between the excited state of encapsulated rhenium complexes and the adsorbed CO2 was observed in photoluminescence spectra, The radicals of rhenium complexes encapsulated in NaY and AlMCM-41 were produced with photoirradiation and confirmed by DR UV-vis spectra, By monitoring the photoreaction of CO2 over the molecular-sieve-encapsulated rhenium complexes using FTIR spectroscopy and gas chromatography, the conversion of CO2 into CO and carbonate species was observed. The molecular-sieve-encapsulated rhenium complexes showed photocatalytic activity for the activation and reduction of CO2, Copyright (C) 2000 John Wiley & Sons, Ltd.
