| 摘 要： | 本文合成了具备水滑石结构(LDH)的Zn-Cr LDH、Zn-Ti LDH以及Ag3PO43种半导体光催化剂,并对它们的催化性能进行对比研究。XRD和SEM分析表明,Zn-Cr LDH、Zn-Ti LDH具有层状结构而Ag3PO4呈纳米球状结构。UV-Vis分析表明,Ag3PO4和Zn-Cr LDH能够吸收可见光(>420 nm)。在可见光照射与添加AgNO3作为电子受体的条件下,Zn-TiLDH几乎没有光催化活性,而Ag3PO4的光催化活性高于Zn-Cr LDH。Ag3PO4在光解水实验中180 min内氧气产量约1.2mL,而Zn-Cr LDH约为0.65 mL。光催化降解有机污染物实验中,在Ag3PO4催化作用下,120 min内亚甲基蓝(MB)被完全降解,在240 min内46%的对硝基酚(PNP)被降解,而Zn-Cr LDH相应的去除率分别为61%和27%。
