a SEM image of 30TiO2 surface before exposure. b SEM image of 30TiO2 surface after 24 h exposure to Na2CrO4 solution in water/acetone at 60 °C. c SEM image of 30TiO2 cross section before exposure. d SEM image of 30TiO2 cross section after 24 h exposure to Na2CrO4 solution in water/acetone at 60 °C. e Comparison of EDS spectra measured at the cross section at 1/2 of the 30TiO2 film thickness before and after exposure to the Na2CrO4 solution in water/acetone mixture for 24 h at 60 °C. The thickness of the film is 100 µm.
