Transient X-ray absorption spectra at Ni K-edge.

(a) XANES spectra of RuN3/Ni(OH)2 hybrid at Ni K edge before (laser-off) and after (laser-on) laser excitation. Inset shows the spectra at 8.3415–8.3417 keV range. The difference spectra obtained from subtracting the laser-off XANES spectrum from laser-on spectrum (5 ns) for RuN3/Ni(OH)2 hybrid (red solid line) and free Ni(OH)2 NPs (gray solid line) are presented below the XANES spectra. (b) The time dependence of the transient signal at 8.3420 keV as a function of delay time.
