摘要:
为获得可见光响应的高效过硫酸盐(Persulfate, PS)活化剂,以莫来石型铁酸铋(Bi 2Fe 4O 9)微米棒为衬底,通过水热法在其表面负载氢氧化镍(Ni(OH) 2),随后将2 甲基咪唑钴(ZIF 67)沉积在Bi 2Fe 4O 9/Ni(OH) 2表面,并与Ni(OH) 2发生原位刻蚀反应形成网状钴镍层状双氢氧化物(CoNi LDH),制得Bi 2Fe 4O 9/CoNi LDH复合材料;通过SEM、XRD、XPS和UV Vis等方法对材料进行表征,考察了Bi 2Fe 4O 9/CoNiLDH材料在可见光下活化PS降解罗丹明B(Rh B)的性能,并通过自由基淬灭实验确定了主要活性物质。结果表明:2-甲基咪唑的添加量对复合材料的形貌和活化性能有显著影响,以0.50 mmol 2甲基咪唑所制备的Bi 2Fe 4O 9/CoNiLDH复合材料(BCN 2)具有1.92 eV的窄带隙,在可见光( λ >420 nm)和2 mmol/L的PS作用下,60 min内可将20 mg/L的Rh B降解98.1%,并且在pH值为3~9的环境中均能保持96.5%以上的降解率。自由基淬灭实验证明主要活性物质为SO 4 · 和 1O 2。该研究为制备过渡金属基复合材料过硫酸盐催化剂提供了新途径。
