Effective photoconversion of CO2 into CH4 over Ti30Si70MCM-41 nanoporous catalyst photosensitized by a ruthenium dye
E-mail:
Nanoporous Ti30Si70MCM-41 was applied as a photocatalyst for effective reduction of CO2 to CH4. A ruthenium dye (N719) was also introduced onto the surface of Ti30Si70MCM-41 as a photosensitizer to improve its photoabsorption in the visible range. The catalytic performance of N719-photosensitized Ti30Si70MCM-41 was superior to that of the non-photosensitized Ti30Si70MCM-41 and N719-photosensitized Ti30Si70O200 nanomaterials. The photoreduction of CO2 to CH4 was remarkably improved on N719-(5 h)-photosensitized Ti30Si70MCM-41, with a production of 1,900 μmol gcat -1 L-1 after an 8 h reaction. The results were attributed to the effective charge separation and the inhibited recombination of photogenerated electron-hole pairs on N719-photosensitized Ti30Si70MCM-41. Lastly, a model for the enhanced photoactivity over N719-photosensitized Ti30Si70MCM-41 was proposed.
