以5，5-二甲基-1-吡咯啉-N-氧化物（DMPO）为自旋捕获剂，用EPR波谱研究了四（4-羧基苯基）卟啉（TCPP）吸附在二氧化钛（TiO 2）上，在可见光照射下产生超氧阴离子O-2（中心点-）的过程.使用化学滤光片去除波长为
The generation of superoxide radical anion O-2(center dot-) from tetra(4-carboxyphenyl)porphyrin (TCPP) adsorbed on TiO2 in DMSO and irradiated by visible light was studied using EPR spectroscopy and 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as spin trap. A chemical filter was used to remove light with wave lengths
