Owing to their excellent electron-accepting capacities, fullerene derivatives have been extensively used as n-type semiconductors. This work reports that the fulleropyrrolidine functionalized with 4,7-di(thiophen-2-yl)benzo[c][1,2,5]thiadiazole, abbreviated as DTBT-C60, could efficiently catalyze the photoreduction of CO2 to CO. The novel C60-chromophore dyad structure facilitated better usage of solar light and effective dissociation of excitons. Consequently, the DTBT-C60 exhibited a promising CO yield of 144 μmol gcat?1 under AM1.5G solar illumination for 24 h. Moreover, the isotope experiments demonstrated that water molecules could function as an electron source to reactivate DTBT-C60. Impressively, DTBT-C60 exhibited an extremely durable catalytic activity for more than one week, facilitating the practical application of photochemical CO2 reaction. ? 2022 Wiley-VCH GmbH |
