The isotherms of water on titania sometimes, but not always, exhibit an unusual feature (Dawson, Parfitt and co-workers ) in the form of a second knee X in the pjp° range 0-2 to 0-3, in addition to a rather rounded knee (cf. D in Figs. 5.21 and 5.22) at a lower relative pressure p/p° 0-05. 

In Fig. 5.21, from Dawson s paper, the uptake at X for the 250°C-outgassed sample is dose to the calculated value for a monolayer of water with a (H20) = 101 A. Point X has therefore been ascribed to a close-packed monolayer of water on a hydroxylated surface of rutile. The fact that the differential entropy of adsorption relative to the liquid state (calculated from the isosteric heat of adsorption) changes sharply from negative to positive values in this region with A s 0 at X was regarded as supporting evidence. ...
