摘要

The photocatalytic autoxidation of S₄O₆^2- and S₂O₃^2- by water- soluble porphyrin complexes Fe(2-TMPyP), Mn(4-TMPyP), and Co(2-TMPyP) were compared under illumination with a 419 nm visible light in oxygen-saturated aqueous solutions at room temperature. The process involves S₂O₃^2- as an intermediate product and SO₄^2- is the final oxidation product. The trend in photocatalytic activity of the porphyrin complexes for S₄O₆^2- oxidation is Co(2-TMPyP) > Mn(4-TMPyP) > Fe(2-TMPyP). For S₂O₃^2- oxidation, the trend is Co(2-TMPyP) > Fe(2-TMPyP) > Mn(4-TMPyP).
