Fig. 1: Structure and morphology characterisation of LTON.
From: Examining the surface evolution of LaTiOxNy an oxynitride solar water splitting photocatalyst
a Crystal structure of LaTiO2N. b XRD pattern of the epitaxial LTON film, the θ/2θ is shown in black, with LaTiO2N and MgO substrate reflexes shown below in red and green for reference. Reflections are labelled using the (hkl) notation. c TEM cross section of the LTON–TiN film grown on MgO. The scale is 100 nm. d High-angle annular dark-field (HAADF) image; a grain boundary (GB) is tracked with asterisks. The scale is 5 nm. e O:N ratio determined by the TEM/EELS analysis; the scale is 100 nm.
