High-pressure photocatalytic reduction of carbon dioxide using [fac-Re(bpy)(CO)3P(OiPr)3]+ (bpy = 2,2′-bipyridine)
摘要:
Photocatalytic CO2-to-CO reduction using [fac-Re(bpy)(CO)(3)P((OPr)-Pr-i)(3)](+) (bpy = 2, 2'-bipyridine) occurred with high efficiency in a high-pressure CO2 gas/organic solvent system. At a CO2 pressure of 1.36 MPa, the turnover number for CO formation was 3.8 times that in the conventional normal-pressure (0.10MPa) system. Application of high-pressure CO2 gas greatly increased the CO2 concentration in the solvent phase. The high CO2 concentration enhanced the reaction of one-electron-reduced catalytic species with CO2, and effectively prevented the deactivation of the catalyst. (C) 2002 Elsevier Science B.V.

Rhenium-bipyridine complexes soluble in compressed CO2 were prepared and employed in the first example of photochemical reduction of CO2 mediated by metal complexes in compressed CO2, without use of an organic liquid solvent.
