Caesium oxide

The catalytic activity of doped nickel oxide on the solid state decomposition of CsN3 decreased [714] in the sequence NiO(l% Li) > NiO > NiO(l% Cr) > uncatalyzed reaction. While these results are in qualitative accordance with the assumption that the additive provided electron traps, further observations, showing that ZnO (an rc-type semi-conductor) inhibited the reaction and that CdO (also an rc-type semi-conductor) catalyzed the reaction, were not consistent with this explanation. It was noted, however, that both NiO and CdO could be reduced by the product caesium metal, whereas ZnO is not, and that the reaction with NiO yielded caesium oxide, which is identified as the active catalyst. Detailed kinetic data for these rate processes are not available but the pattern of behaviour described clearly demonstrates that the interface reactions were more complicated than had been anticipated. 

TPD that Cs loadings above 3% showed a significant decrease in the basicity of the catalyst, suggesting the growth of caesium oxide particles.

Caesiiun azide melts with little decomposition (<1%) at 598 K. Slow decomposition was observed [45] when semiconducting oxides such as NiO were present in large amounts and was autocatalysed by caesium oxides formed in the reaction. The photochemical decompositions of both salts have been investigated [46],... 

Molecular dynamics calculations have been made on the motions of the Na+ ion in mordenite zeolites.9 Selenium clusters doped with Na (i.e. Na2Sen) show a Raman band in the range 165-225 cm 1 due to Na-Se motions.10 Raman microspectra have been reported for caesium oxides, e.g. an alg mode of Cs20 was seen at 103 cm 1.11...
