Figure 5.9. IR spectra of the activated samples Cu/Pd-BTC_1-3 in comparison with the parent<br />

Cu-BTC as well as H 3 BTC and Pd-acetate.<br />

Furthermore, any vibrations stemming neither from the non-reacted H3BTC linker nor<br />

used metal-precursors (i.e., acetate-, nitrate-groups) could be revealed in the FT-IR
