制备了一种负载有纳米 Ti O2 微粒能漂浮在水面与原油接触的光活性催化剂 .测定了用这种光催化剂在紫外光源照射下对水面原油的光催化降解速率 .报道了直接在太阳光照射下对水面原油的光催化降解实验结果 .实验表明 ,Ti O2 光催化不仅能有效的降解水面石油污染物 ,并能抑制原油在自然氧化过程中形成的有害共聚物 .
A kind of photoactive catalyst supported on nano-TiO 2 particles which could float on the surface of water and contacted with crude oil was prepared.The photocatalytic degradation rate of crude oil on water surface with this kind of photocatalyst under ultraviolet light source was measured, The experimental results show that Ti O2 photocatalytic can not only effectively degrade the surface petroleum pollutants, but also inhibit the formation of harmful copolymers of crude oil during natural oxidation.
