‘‘White line’’ in the chlorine K x-ray absorption spectra of K2PdCl4, K2PtCl4, K2PdCl6, and K2PtCl6

Abstract

The chlorine K absorption spectra from complex compounds K2PdCl4, K2PtCl4, K2PdCl6, and K2PtCl6 have been obtained with a 50 cm bent-quartz crystal vacuum spectrograph. An intense ‘‘white line’’ has been found at the absorption threshold and shows the chemical shift which is closely related with the ionization potentials of Pd and Pt, corresponding to the transition from the chlorine 1s level to the lowest unoccupied antibonding orbital originating from the Pd 4d or Pt 5d and Cl 3p orbitals. The other absorption structures are alike throughout four compounds. A tentative explanation for the absorption structures near the K edge is made in terms of the core level-to-empty state transitions in the Cl− ion. Radiation effect is found on the chlorine K absorption spectrum of K2PdCl6.

“…The SE particles were prepared by pulverizing the as-prepared SE in heptane and dibutyl ether using small zirconia balls (200 g, 2 mm in diameter). 5 NMC 6,7 with the average size of about 5 μm was used as a typical positive electrode material. 8 The NMC particles were coated with LiNbO 3 in advance to decrease the interfacial resistance between NMC and SE.…”
