| 摘 要： | A series of Ti1-xZrxO2 materials were synthesized through a multistep sol-gel process. The structural characteristics were investigated using X-ray diffraction （XRD）, X-ray photoelectron spectroscopy （XPS） and Raman measurements. The experimental results showed that a solid solution could be obtained at low Zr/（Ti＋Zr） molar ratios （x ≤0.319）. Raman measurements exhibited that the presence of zirconium in the solid solutions greatly retarded the amorphous-anatase and anatase-rutile transitions. The diffuse reflectance UV-Vis spectra revealed that the bandgap of the solid solution was enlarged gradually with the increment of incorporated zirconium content. The Ti1-xZrxO2 solid solutions exhibited higher photocatalytic activity than pure TiO2 for the degradation of 4-chlorophenol aqueous solution.

| Abstract: | A series of Ti1?xZrxO2 materials were synthesized through a multistep sol‐gel process. The structural characteristics were investigated using X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS) and Raman measurements. The experimental results showed that a solid solution could be obtained at low Zr/(Ti+Zr) molar ratios (x≦0.319). Raman measurements exhibited that the presence of zirconium in the solid solutions greatly retarded the amorphous‐anatase and anatase‐rutile transitions. The diffuse reflectance UV‐Vis spectra revealed that the bandgap of the solid solution was enlarged gradually with the increment of incorporated zirconium content. The Ti1?xZrxO2 solid solutions exhibited higher photocatalytic activity than pure TiO2 for the degradation of 4‐chlorophenol aqueous solution. |
