X theory is capable of very simply explaining the results obtained from isotherms that do not seem to foUow the standard isotherm model. It is straightforward and consistent with the entire theoretical framework of the x theory. [Pg.154]

Heat of adsorption is an area where the x theory is clearly superior to other theories of adsorption. The Dubinin concept of adsorption potential and the [Pg.154]

A few examples of the predictions of x theory to yield the various defined heat of adsorption are presented here. Other examples and more detail can be found in an article on the subject [30]. In order to make a parameterless prediction of the isosteric or integral heat of adsorption, an adsorption isotherm is first obtained. If there are no complicating features, such as simultaneous chemisorption or microporosity, then these heat of adsorptions can be predicted without any further information. (This is what is referred to as a parameterless prediction or fit. That is, all the constants needed to make a calculation are available from some other measurements.) [Pg.155]

One of the problems encountered in the literature is that the data have been transformed and presented in such a way that it is difficult, if not impossible, to unscramble the presentation to obtain the original data. Luckily, some can be obtained directly, as is the case with data by Pace et al. [31,32], from original sources, such as PhD dissertations [33,34], or mathematically unwinding it as is the case with information supphed by Harkins and Jura [35]. Fig. 89 shows the molar integral heat of adsorption of water on anatase as obtained [Pg.155]

An issue that is being considered with attention concerns the possibility to achieve multiple electron transfers on the first wave of POMs. The aim is twofold (1) save energy by favoring those electro-catalytic processes that necessitate several electron to be performed (2) avoid the... [Pg.662]
