Description
技术领域
本发明涉及空气净化技术领域,尤其涉及一种可见光催化氧化去除异味复合材料的制备方法及应用。
背景技术
目前,国内外制备具有选择性光催化降解有机污染物的催化剂的研究取得了一定的进展。各类方法中对各类有机污染物均适用并具有较高选择性的还是首推分子印迹技术。虽然利用分子印迹TiO2进行选择性降解低浓度高毒性有机污染物方面已取得一些进展,但目前针对这一新型材料的研究还属于刚刚起步,尤其是性能更优越、更有前途的材料正在开发之中。
越来越多的人注意到了环境质量的重要性尤其是室内空气质量,特别是空气中包含的甲醛、苯类以及其他一些有特殊气味的有机污染物。传统的应对他们的方法有物理吸附法、化学氧化法、微生物处理法,还有种植一些具有针对性吸收作用的盆栽。各种各样的产品层出不穷,并且还在不断的推陈出新。但这些方法大部分都有他们的局限性。比如降解目标单一,降解性能低下,容易产生二次污染等,所以应用效果有限。C3N4和金属氧化物是两种能够利用光进行催化降解的光催化剂。他们的热力学性能稳定,可以利用半导体材料在光照下表面能受激活化的特性,利用光能可有效地氧化分解有机物、还原重金属离子、杀灭细菌和消除异味,因而受到越来越多的重视。可见光催化作为一种新兴且强大的有机合成手段,具有洁净节能、优秀的官能团兼容性和良好的化学选择性等特征。氧气作为一种廉价、无污染的氧化剂,与可见光催化相结合,极大地促进了绿色化学的发展。
利用各种性能优良的改性选择性吸附材料(石墨烯,导电聚合物,活性炭,沸石,硅藻土,碳纳米管,蒙脱石等)与TiO2杂化,制备具有高选择性高吸附性能的光催化材料也可能是一种途径。通过光催化降解低浓度、高毒性有机污染物是未来空气净化领域的重要研究方向。
针对以上技术问题,本发明公开了一种可见光催化氧化去除异味复合材料的制备方法及应用,本发明制备的可见光催化氧化去除异味复合材料比表面积高、吸附位点多、吸附性能好,催化氧化性能优异,具有洁净节能、优秀的官能团兼容性和良好的化学选择性等特征,制备工艺简单,实用性强,可利用廉价、无污染的氧气作为氧化剂,与可见光催化相结合,符合我国绿色化学发展方向。

对制备得到的可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3进行孔结构特征和表面结构性质的表征,以及吸附性能测试。
(一)分别测试可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的氮气吸脱附性能、孔径分布及孔结构参数,氮气吸脱附性能曲线图如图2,孔径分布图如图3,孔结构参数表见表1。
表1 ZC1、ZC2、ZC3的孔结构参数表
其中,Dap(nm)表示平均孔径,单位为nm;SBET(m2/g)表示比表面积,单位为m2/g;Smic(m2/g)表示微孔比表面积,单位为m2/g;Vt(cm3/g)表示总孔容,单位为cm3/g;Vmic(cm3/g)表示微孔孔容,单位为cm3/g。
由图2可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的氮气吸脱附曲线图,可以看出在0–0.1相对分压下,复合材料对氮气的吸附量快速增加,说明有小于2nm的微孔存在;0.1–0.4相对分压下,复合材料对氮气的吸附量保持平衡,说明有大量2-50nm的中孔;在相对压力下高的情况下,吸附曲线和脱附曲线不再重合,二者出现了明显的滞后环现象,为I型和IV型特征的结合,说明存在一定量的微孔和中孔。
由图3可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的氮气孔径分布图可以看出微孔、中孔分布,说明可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3同时具备微孔和介孔结构,这些结构有利于异味气体的吸附;可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3孔径分布在0~50nm。
由表1可知,可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的平均孔径在3.21~3.74nm之间;随着制备比例的变化,可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的比表面积先减小后增大,ZC1的比表面积最大;可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3既含有微孔部分,也含有介孔部分,这些微孔和介孔周围都分布着光催化材料,在可见光下,可以将孔道吸附进来的有机气体迅速被氧化降解,避免了空气被二次污染。
(二)可见光催化氧化去除异味复合材料ZC3扫描电镜图见图4。
由图4可见光催化氧化去除异味复合材料ZC3的扫描电镜图可知活性炭表面存在着大量的孔道,这些孔道对于异味吸附有着非常重要的作用,丰富的孔道结构对于吸附不同种类的气体有着不同的作用,有利于对异味的有效去除。复合材料表面丰富的孔道结构是复合材料吸附异味气体分子的关键所在,二氧化钛粉末、四氧化三钴粉末、氧化铝粉末、五氧化二钒粉末、纳米氧化锌粉末、纳米氧化镁粉末等光催化材料对于异味能快速的催化降解,使被污染的空气变得更加洁净。
(三)经测试可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的颗粒强度分别为36、45、55N/㎡;可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的pH值分别为5.75、6.18、7.22;可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3对异味的去除率详细见表2:
表2可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3的对碱性VOCs的去除率表
可见光催化氧化去除异味复合材料ZC1、ZC2、ZC3对VOCs有很好的去除率,综合去除率分别为98.3%、95.3%、96.8%。
