Fig. 7: The comparison of the time profiles between major features at the oxygen K-edge and the Ti L-edge.

The comparison between the kinetic trace of (a) A at the oxygen K-edge and Ti3+ at the Ti L-edge for SC, (b) B and C at the oxygen K-edge and Ti4+ at the Ti L-edge for SC, (c) A at the oxygen K-edge and Ti3+ at the Ti L-edge for NC, (d) B and C at the oxygen K-edge and Ti4+ at the Ti L-edge for NC.
