Synthesis and photocatalytic activity of K 2 CaNaNb 3 O 10 , a new Ruddlesden–Popper phase layered perovskite

evolution was much lower when 1-propanol was used as an electron donor than when methanol was used. In contrast, the R-P phase exhibited a similar activity regardless of the electron donor. These results indicate that the interlayer space acts as an oxidation site, so that better access of the electron donor to the interlayer is an important factor that enhances photocatalytic activity.
