h-BN-TiO₂ Nanocomposite for Photocatalytic Applications

Figure 3

Correlated tapping mode (a-b) topography AFM images and (c-d) charge EFM images before and during UV irradiation of samples h-BN-TiO₂. The change in the signal between images (b) and (d) is positive charging of h-BN-TiO₂ under UV light.
