They are characterized by a notably strong texture and their Ti (0002) plane lies parallel to the rod axis (Figure 1B,C and Figures S1F and S2, Supporting Information), i.e., their basal planes face outside.
Unlike other hydrohalic acids, such as hydrochloric acid, hydrogen fluoride is only a weak acid in dilute aqueous solution. This is in part a result of the strength of the hydrogen–fluorine bond, but also of other factors such as the tendency of HF, H 2O, and F anions to form clusters. At high concentrations, HF molecules undergo homoassociation to form polyatomic ions (such as bifluoride, HF 2) and protons, thus greatly increasing the acidity. This leads to protonation of very strong aci…
