Nb₂O₅/t-ZrO₂ catalysts with different loadings were prepared by aqueous solution impregnation using niobium oxalate as a precursor on tetra nal ZrO₂ (t-ZrO₂). The dispersion states with respect to niobia species on t-ZrO₂ were characterized by powder X-ray diffraction (XRD), laser Raman spectroscopy (LRS), and UV visible diffuse reflectance spectroscopy (UV-Vis DRS). The catalytic activity was evaluated by the condensation reaction of iso-butene (IB) and iso-butyraldehyde (IBA) to 2,5-dimethyl-2,4-hexadiene (DMHD) and the Brønsted acidity was evaluated by the Fourier-transform infrared spectroscopy of pyridine adsorption (Py-IR). The results reveal that the dispersion capacity Γ_Nb of Nb₂O₅ on t-ZrO₂, which was determined by XRD quantitative phase analysis, is almost identical to the value predicted by the "incorporated model". The results also show that the Brønsted acid sites are strongly related to the states of Nb₂O₅ on Nb₂O₅/t-ZrO₂.
