摘要
以粉煤灰成型吸附剂为载体,采用液相沉淀法制备粉煤灰成型吸附剂负载TiO2光催化剂,并对其光催化性能进行研究。结果表明,在有可见光照射的条件下,当吸附剂的投加量为8 g/L、催化剂的焙烧时间为2 h、溶胶的pH值为9时,粉煤灰成型吸附剂负载TiO2光催化剂对亚甲基蓝(MB)的催化效率最高。
Taking the fly ash adsorbent as carrier, titanium dioxide （TiO2） photocatalyst coated on fly ash adsorbent was prepared by liquid precipitation method, and its photocatalytic performance was studied. The results show that under the condition of light irradiation, when the adsorbent dosage is 8 g/L, catalyst calcination time is 2 h and the pH value of gel is 9, the highest degradation efficiency of methylene blue by TiO2 photocatalyst coated on fly ash adsorbent is reached.
