In this study, the catalytic properties of lanthanum modified V₂O₅ catalyst for SO₂ oxidation have been studied. Effects of La₂O₃ content and reaction temperature were investigated to optimize La₂O₃ loading on V₂O₅ catalyst. The samples were characterized by BET, FT-IR, Raman, XRD, SEM and TG/DSC. The results showed that the catalyst with 4 wt% La₂O₃ (VLa4) possessed the highest catalytic performance, improving the mean SO₂ conversion at least 53% compared with the catalyst without La₂O₃ (VLa0). Due to its excellent low-temperature and high-temperature activities, VLa4 catalyst appears to be more efficient for the conversion of highly concentrated SO₂ gases.

在这项研究中，研究了镧改性的V ₂ O ₅催化剂对SO ₂氧化的催化性能。研究了La ₂ O ₃含量和反应温度对优化La ₂ O ₃在V ₂ O ₅催化剂上的负载量的影响。通过BET，FT-IR，拉曼，XRD，SEM和TG / DSC对样品进行表征。结果表明，与4重量％的La的催化剂₂ ø ₃（VLA4）具有最高的催化性能，提高了平均SO ₂转化率与没有La上的催化剂相比至少53％₂ ö ₃（VLa0）。由于其出色的低温和高温活性，VLa4催化剂似乎对于高浓度SO ₂气体的转化更为有效。
