Zirconia itself is inactive for this type of reaction and becomes active only through addition of sulfate. Optimization of the sulfate content has been performed empirically [2], but it is e.g. not known whether complete coverage of the zirconia surface with sulfate is desirable or whether sites on the zirconia itself play a role in the reaction scheme. The goal of this work was to develop a method to detect free zirconia surface, to quantify its extent depending on the preparation procedure, and to assess the role of such sulfate-free areas of zirconia for the interaction with alkanes. 1.P.T.
