Description
技术领域
本发明涉及环境污染控制新材料的开发,尤其涉及一种可磁力分离的氧化银催化剂的制备方法。
背景技术
水滑石类化合物(LDHs)是由层间阴离子及带正电荷层板堆积而成的化合物。水滑石化学结构通式为:[M2+ 1-xM3+x(OH)2]x+[(An-)x/n·mH2O],其中M2+和M3+分别为位于主体层板上的二价和三价金属阳离子,如Mg2+、Ni2+、Zn2+、Mn2+、Cu2+、Co2+、Pd2+、Fe2+等二价阳离子和Al3 +、Cr3+、Co3+、Fe3+等三价阳离子均可以形成水滑石;An–为层间阴离子,可以包括无机阴离子,有机阴离子,配合物阴离子、同多和杂多阴离子;x为M3+/(M2++M3+)的摩尔比值,大约是4:1到2:1;m为层间水分子的个数。其结构类似于水镁石Mg(OH)2,由八面体共用棱边而形成主体层板。位于层板上的二价金属阳离子M2+可以在一定的比例范围内被离子半价相近的三价金属阳离子M3+同晶取代,使得层板带正电荷,层间存在可以交换的的阴离子与层板上的正电荷平衡,使得LDHs的整体结构呈电中性。层间的阴离子可被交换,经过一系列改性,水滑石材料可以得到许多种性能各异的物质。
通过离子交换等方式把一些化合物引入层间域,形成分子级别的支柱,制成的一类孔径大、分布规则的新型分子水平复合材料,具有吸附、转化有机分子的特点。水滑石品种多,支柱化合物的可调性,改性后的粘土材料孔径大小、吸附性质等可以人为加以控制,因此可以根据用途的不同来进行材料制备,在石油化工、环境保护等诸多领域有广泛应用前景。
氧化银(Ag2O)是一种p型半导体,其带隙能为1.46eV,在可见光区内有较强的光吸收,是一种高活性和高选择性的窄带隙光催化剂。但是氧化银在光照后导带产生的光电子会将Ag+还原成Agn单质簇,而价带的空穴会氧化晶格中的O2-释放O2,所以会产生催化剂本身的光腐蚀现象。同时氧化银纳米粒子中的银离子将和残留的一部分氧结合,其晶格将发生重构,从而产生各种类似分子的光解发光中心。光解中心的出现将在氧化银的禁带中引入若干缺陷能级,从而使得氧化银纳米粒子利用光子效率提高。在光腐蚀的过程中,当单质银和氧化银的相对含量达到一定值时,后续会保持稳定性。
催化作用后存在分离困难的问题,如果要分离干净,需要经过多个步骤,费时费力。
发明内容
本发明的目的是为克服现有技术中氧化银结构单一的不足,提供一种可磁力分离的氧化银催化剂的制备方法。
本发明采用的技术方案是依次包括如下步骤:
1)将FeCl2溶解到水中,配置为浓度为2~3mol/L的溶液,取500mL该溶液,将其置于恒温70~80℃水浴中,同时滴加质量分数30%的双氧水2~4mL和一定量的NaOH稀溶液,保持pH值为12~13,反应2~3h,转入高压釜中,在1h内升温到150~180℃,继续反应4~8h,自然冷却到室温,在该过程中形成具有层状结构的沉淀,沉淀分离,去离子水洗2~3遍;
2)将沉淀得到的固体加入到浓度为2~4mol/L的十二烷基苯磺酸钠溶液中,固液比为1:10~1:50,在50~80℃水浴中搅拌2~8h,磁场分离后用去离子水洗涤2~3遍,70~90℃烘干,得到磁性有机水滑石。
3)将(3-氨基丙基)三乙氧基硅烷、水杨醛和硝酸银按摩尔比1:1:1的量各2~4mol加入到20~40mL水中形成溶液,在20~35℃下反应6~8h,加入磁性有机水滑石,搅拌2~4h、沉淀分离,反应生成的含银有机配合物在分配作用下,形成含银有机配合物柱撑水滑石;
4)将含银有机配合物柱撑水滑石置于马弗炉中,400~550℃下焙烧6~8h,其中的碳氮等元素转化为气体溢出,形成孔道,得到一种可磁力分离的氧化银催化剂。
本发明的优点是:部分二价铁离子被双氧水氧化生成的三价铁,二价离子和生成的三价离子在70~80℃水浴中碱的作用下,产生磁性共沉淀,形成片层水滑石结构,再在片层间交换入表面活性剂,使其表面由疏水性转变为亲水性,植入相应的银化合物,最后经过煅烧,烧去C、N等物质,得到具有磁性的多孔氧化银材料。铁银之间会有协同作用,能更好的促进催化作用。

2)将沉淀得到的固体加入到浓度为2~4mol/L的十二烷基苯磺酸钠溶液中,固液比为1:10~1:50,在50~80℃水浴中搅拌2~8h,磁场分离后用去离子水洗涤2~3遍,70~90℃烘干,得到磁性有机水滑石;
3)将(3-氨基丙基)三乙氧基硅烷、水杨醛和硝酸银按摩尔比1:1:1的量各2~4mol加入到20~40mL水中形成溶液,在20~35℃下反应6~8h,加入磁性有机水滑石,搅拌2~4h、沉淀分离,反应生成的含银有机配合物在分配作用下,形成含银有机配合物柱撑水滑石;
4)将含银有机配合物柱撑水滑石置于马弗炉中,400~550℃下焙烧6~8h,其中的碳氮等元素转化为气体溢出,形成孔道,得到一种可磁力分离的氧化银催化剂。
