卟啉及金属卟啉具有良好的光和热稳定性，其吸收光谱在可见光范围内，具有许多独特的物理、化学性质及其它功能性质，因而在生物化学、药物化学、分析化学、光化催化和材料科学等领域都得到广泛的关注和应用。

However, as photocatalyst TiO_2 has two shortcomings: first it has only a narrow responding width to natural light and then a rapid combination velocity of the stimulated excisions. So it has not high catalytic activities.

TiO_2是最常用的光催化剂，但是由于对自然光响应波长范围窄，光生载流子复合过快而催化活性不高。

It was found that the main reason why SBS containing oil was easy to yellow was that there is plenty of polycyclic aromatic hydrocarbon in the extender oil,PAH can easily turned quinones with yellow.Antiyellowing performance of SBS can be only developed in a little extent when antioxidants were added.The anti-yellowing performanc...

研究结果表明，充油SBS产品变黄的主要原因是油品中的稠环芳烃在光氧环境中易转化为黄色的醌，添加抗氧剂对延缓产品变黄的作用不大，通过催化加氢消除填充油中的芳烃或添加适当的光稳定剂可以提高产品的耐黄变性能。
