A. F. Gualdrón–Reyes, A. M. Meléndez, I. González, L. Lartundo–Rojas, M. E. Niño–Gómez. Effect of metal substrate on photo(electro)catalytic activity of B–doped graphene modified TiO2 thin films: Role of iron oxide nanoparticles at grain boundaries of TiO2. J. Phys. Chem. C 122 (1) (2018) 297–306.

Grain-boundary nanosegregation of alpha–FeOOH and alpha-Fe2O3 in TiO2 films cause deleterious effect on photocatalytic and photoelectrocatalytic activity. Electron scattering at grain boundaries contributes to increasing the resistivity of the semiconductor film, affecting strongly electron diffusion inside the film.
