In this study, the electronic structure of CuBi2O4 has been studied by a combination of hard X-ray photoemission, resonant photoemission and X-ray absorption spectroscopies, and compared with density functional theory (DFT) calculations. The photoemission study indicates that there is a strong Bi 6s-O 2p hybrid electronic state at 2.3 eV below the Fermi level, whereas the valence band maximum (VBM) has a predominant Cu 3d – O 2p hybrid character. XAS at the O K-edge...
