在Co-TPP-TiO_2上用一氧化碳还原氧化氮,50℃的速率比氢大得多,100℃的速率就更为迅速。这表明了一氧化碳和氧化氮在负载络合物部份还原的Co离子上得到了有效的活化。以前,我们曾报导过在二氧化钛上负载钴-四苯基卟啉时,产生由电子转移引起的强烈的相互作用(由紫外光谱和电子自旋共振光谱揭示)使其在中等反应温度(约150℃)下用氢还原氧化氮的催化活
Reduction of nitrogen oxides with carbon monoxide on Co-TPP-TiO 2 is much faster at 50 ° C than hydrogen at 100 ° C. This shows that carbon monoxide and nitric oxide are effectively activated on Co ions that partially reduce the supported complex. We have reported previously that when cobalt-tetraphenylporphyrin is supported on titanium dioxide, a strong interaction due to electron transfer (as revealed by UV-Vis and electron spin resonance spectroscopy) is caused to occur at moderate reaction temperatures (about 150 ° C) with hydrogen reduction of nitrogen oxide catalytic activity
