Abstract
Two families of anatase nonporous particles of various diameters (or surface area), differing in their shape, namely, spherical or polyhedral, give two distinct compensation effect laws when, for the catalytic oxidation of carbon monoxide, the logarithm of the preexponential factor is plotted as a function of the activation energy. This behavior, which is found when anatase is activated in vacuum or in hydrogen, before the catalytic reaction, is no longer observed if the activation is carried out in carbon monoxide (noncompensation effect). The nature of active sites involved after each activation is discussed and the effect of catalytic “heredity” is examined in an attempt to correlate the catalytic activity in “demanding” and “facile” reactions with some other properties of oxide catalysts.
