Fig. 3: Photocatalytic CO2 conversion to methanol.

From: Unique hole-accepting carbon-dots promoting selective carbon dioxide reduction nearly 100% to methanol by pure water

Fig. 3

The photocatalytic activity of a mCD/CN and b sCD/CN measured under visible light (λ > 420 nm). c Control experiments on mCD, sCD, CN, mCD/CN and sCD/CN. Error bar: mCD/CN 13.9 ± 1.7 µmol/g/h, sCD/CN 1.2 ± 0.2 µmol/g/h. d Mass spectra of the product 13CH3OH from 13CO2 photoconversion by the mCD/CN photocatalyst. Inset: the mass spectra of the 13CO from 13CO2 photoconversion over the mCD/CN photocatalyst. e Consecutive three runs of CO2 photoconversion to methanol on mCD/CN under visible light. f IQY of mCD/CN measured at atmospheric pressure under nearly one sun irradiation condition. Source data are provided as a Source Data file.
