| 摘 要： | 利用本实验室制备的N-F原子掺杂二氧化钛纳米管作催化剂,在可见光区对甲基橙(MO)进行光催化降解实验。在催化剂用量固定为3cm2时考察了不同初始浓度、pH值、溶解氧(DO)等对降解率的影响。结果表明,在可见光区该催化剂具有较高的光催化活性;当溶液DO为19.2mg/L、pH值为3、初始浓度为10mg/L、反应时间300min时,降解率可达82.3%。

| Abstract: | N-F codoped TiO2 nanotubes were used to be degraded methyl orange(MO) in aqueous solution in visible region.In the fixed situation of catalyst dosage(about 3cm2),the effects of the initial concentration of MO,pH value and dissolved oxygen(DO) were investigated.The results indicated that this catalyst had high photocatalytic activity.When the DO was 19.2mg/L,pH was 3,the initial concentration of MO aqueous solution was 10mg/L and reaction time was 300 min,the degradation efficiency reached to 82.3%. |
