摘要：以轻质绝热保温建筑材料膨胀珍珠岩为载体担载纳米二氧化钛得到可长时间漂浮于水面的负载型光催化剂,用于水面浮油的太阳光光催化降解。结果表明,经约7h的太阳光照射,可使96%以上癸烷浮油降解。探讨了二氧化钛在膨胀珍珠岩载体上的成膜和浮油降解机理。
The light expanded perlite (EP), widely used as heat insulation building materials, was (selected) as the carrier for immobilization nano-TiO_2 to prepare buoyant photocatalyst floating on water for a long period. The photocatalytic degradation of decane, a model of spilled oil, was investigated using (solar) energy. The experimental results showed that above 96% of decane was degraded under 7 h irradiation of solar energy with an average intensity of about 2 520 μW/cm^2. The formation mechanism of TiO_2 film on EP and the process of photocatalytic degradation of the spilled oil on the buoyant TiO_2/expanded perlite photocatalyst were analyzed.
