a In situ DRIFTS spectra of TJU-27-Ru during photocatalytic CO2 reduction. In situ high-resolution XPS spectra under light and dark (light: under visible light (λ > 400 nm) illumination) of Ru 3p (b), and Pb 4 f (d) for TJU-27-Ru photocatalyst. c Calculated free energy (ΔG) diagram of TJU-27-Ru for CO2 photoreduction to CO. e Schematic representation of CO2 photoreduction mechanism occurring on TJU-27-Ru.
