采用溶胶-凝胶法和水热法制备了纳米结构V2O5/NTiO2-Al2O3催化剂，并通过XRD、TEM、N2-BET和XPS进行了表征。研究了 TiO2-Al2O3 作为 V2O5 纳米结构载体在高温下对 NO-SCR-NH3 的作用。结果表明，含有 5 wt.% Al2O3 和 5 wt.% V2O5 的 V2O5/NTiO2-Al2O3 催化剂在 200–500 °C 温度范围内具有最高活性，并且没有 NH3 氧化成 NO2。
Nanostructured V2O5/NTiO2–Al2O3catalysts were prepared by the sol–gel and hydrothermal methods and characterized by XRD, TEM, N2-BET and XPS. The role played by TiO2–Al2O3as nanostructured support of V2O5for NO–SCR–NH3at high temperature was studied. The results show that the V2O5/NTiO2–Al2O3catalyst containing 5 wt.% of Al2O3and 5 wt.% of V2O5featured the highest activity in the 200–500 °C temperature interval without NH3oxidation to NO2.
