Effects of Monolayer Dispersion

Oxides or salts in a monolayer state and in their crystalline state behave differently in many respects. Effects of monolayer dispersion show up in spectra as well as in the properties of the oxides and salts.

Samples of Mo03/Ti02 prepared by an impregnation method using a solution of (NH4)2Mo207 have been studied recently by Quincy et al. (39). They obtained a similar plot, which allows us to obtain the same monolayer dispersion capacity, namely, 0.12 g MoO3/100 m2 of Ti02 surface. 

The signal Cu decreases exponentially with time, as is verified by the straight line of In ICu versus time in Fig. 18.
