摘要
以耐火砖颗粒为载体制备了几种不同类型的负载型光催化剂.对其TiO2负载量、催化剂表面形貌等进行了表征.并通过直接耐酸大红(4BS)降解脱色试验,考察催化剂的负载、运行次数以及不同制备方法对催化活性的影响,最终筛选出各项性能较优的负载型光催化剂.
Several different kinds of immobilized photocatalysts were prepared using firebrick granules as carrier. The immobilized photocatalysts were characterized in the amount of TiO2 and the surface of the catalysts. And the 4BS was decolored to investigate the influence of the immobilization, running times and different preparing ways of the catalysts. At last, an immobilized photocatalyst with good performance was selected out.
