Electronic absorption spectra of platinum(II) centers in liquid alkali metal chloridesJournal of Inorganic and Nuclear Chemistry, Volume 35. Issue 3, March 1973. Pages 799-807G. N. Papatheodorou and G. Pedro SmithAbstract
The optical electronic absorption spectra of Pt(II) centers have been measured in liquid CsCl. KCl. LiCl and CsCl---LiCl and KCl---LiCl mixtures over substantial temperature ranges. In CsCl at 650°–700°C and the eutectic mixtures below about 400°C the spectrum is that expected for normal square-planar PtCl
complex anions at elevated temperatures. In LiCl and the mixed solvents at elevated temperatures the spectrum is modified by a drawing together of the two spin-allowed bands. This effect is attributed to the polarization of PtCl
promoted zirconia catalysts prepared by the mixed solution methodApplied Catalysis B: Environmental, Volume 7. Issues 3-4, 18 January 1996. Pages 237-250Ki June Yoon and Sang Won SeoAbstract
Sodium-salt-promoted zirconia catalysts prepared from mixed solutions of zirconyl chloride and sodium salts (chloride change process or sulfate) are found to possess effective catalytic performances in the oxidative coupling of methane. The highest C
The mixed solution method is considered to be an effective preparation method when proper precursor compounds of zirconia and promoters are chosen giving a desirable interaction between them. The reaction and characterization results indicate that the chlorine ion plays a more prominent role than the sodium ion and the X-ray photoelectron spectroscopy results show the presence of multiple chlorine species on the surface. It is suggested that the Cl
