Light-induced charge dynamics pathways and their effect on CO2 photoreduction. Cumulative production of a methane and b methanol under 365 nm and 450 nm irradiation, respectively. c Transmission electron microscopy (TEM) image of Ag nanocluster supported on the anatase TiO2 surface, scale bar 2 nm. d A combination of in situ characterisation tools at different timescales and theoretical calculations allow the determination of the optoelectronic and surface properties at the Ag/TiO2 interface and their effect on photoredox reactions in artificial photosynthesis
