•Electron diffusion was faster in the direction of double hydroxide layer.•CO2 was in equilibrium with HCO3 species for the reaction with hydroxy groups.•Interlayer spacing affected the CO2 diffusion into the interlayer reaction space.•The decomposition of HCO3 under light was enhanced by the additi...
