摘　　要：对SO2在不同气氛和不同类型催化剂上的光催化性能进行研究。研究发现,O2的加入对SO2转化率的影响要大于对生成SO3的影响,而CO气体的加入却对提高SO2转化率和SO3收率均有利。反应的气氛情况和催化剂本身的性能特点是决定SO2光催化反应进行方向的关键因素。The photocatalytic degradation of SO2 has been investigated in different atmospheres. It is found that the conversion of SO2 is influenced by O2 more than the yield of SO3. And the introduction of CO increases both the conversion of SO2 and the yield of SO3. The reaction atmosphere and the property of the catalysts are the decisive factors of the photocatalytic degradation of SO2.
