【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。更多还原

【Abstract】 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.更多还原
