Table 1 Photocatalytic properties of Ru2ReA and RuRe2A. The same properties of Ru2Re and RuRe2 are shown for comparison purposes.

From: Photocatalyzed CO2 reduction to CO by supramolecular photocatalysts made of Ru(II) photosensitizers and Re(I) catalytic subunits containing preformed CO2TEOA adducts

  1. CO2-saturated DMA-TEOA (5:1 v/v), 3 mL solutions containing the supramolecular photocatalysts and a BIH as the sacrificial electron donor (0.1 M). Light irradiation wavelength, 530 nm. The concentration of the photocatalysts containing one Ru-based subunit was 50 µM, whereas the concentration of the photocatalysts containing two Ru-based subunits was 25 µM, unless otherwise stated, to normalize for light absorption in the various experiments. aIn parenthesis, the percentage of CO production vs sacrificial reagent concentration is given; based on the concentration of the sacrificial donor, the theoretical maximum of CO photoproduced is 0.30 mmol. bTurnover numbers are based on the amount of photocatalyst. cConcentration of the photocatalyst was 44 µM. dData from ref.29.
