Description
技术领域
本发明属于化工催化剂领域,具体而言,涉及吸附驱动高级氧化催化剂的制备方法,可以吸附降解低浓度有机污染物。
背景技术
VOCs是空气污染的一大污染源。长期暴露在含有较高浓度VOCs污染的气体中可引起各种健康问题,甚至引起癌症、畸形和突变。传统的热催化氧化技术能耗高,光催化净化技术效率低。光催化复合热催化的光热协同催化净化VOCs技术近些年来受到广泛关注,相比单一的光催化或热催化技术,光热协同催化不仅能同时利用光能和热能,还可通过协同效应增强反应效率。
催化反应过程是一个表面反应过程,对于低浓度特别是痕量污染物的净化过程,传质过程通常成为催化反应的速控步骤,相应的催化氧化过程也一直因为效率低而受到诟病无法得到广泛的应用。为解决这一问题,吸附-催化体系被广泛采用,如通过将多孔结构与高级氧化催化剂复合,可以形成吸附催化复合材料,多孔材料可以先将VOCs富集,高级氧化催化剂产生活性氧(reactive oxygen species,ROS)基团,如OH·自由基等,高能的OH·在扩散到吸附材料层后,能够直接氧化所吸附的VOCs。通过这一ROS媒介的高级氧化过程,可以实现介孔吸附材料吸附性能的原位再生,从而实现了吸附材料快速净化能力与催化氧化材料无二次污染优越性的完美组合。
传统的方法通常是将锰、铈、钛等物质的可溶性盐与氧化铝、铝矾土、硅藻土、高岭土、分子筛等多孔性物质粉体混合后造粒成型,或者这些可溶性盐是在球状、圆柱或者蜂窝状载体上浸渍负载,最后都需要经过高温烧结,盐类转变为氧化物。上述方法中活性组分与载体的结合力较弱易流失,活性组分在高温处理过程中晶体长大而堵塞载体的孔道。专利CN101138715A公开了TiO2-柱撑膨润土吸附-光催化一体化催化剂的制备方法,将膨润土的悬浮液加入到钛酸丁酯的乙醇溶液中混合,烘干后300~550℃煅烧,虽然减少了水、酸用量,但高温烧结易造成晶体长大堵塞,而且粉末状的催化剂在实际应用过程中不易回收重复利用。因此,开发可以具备低温原位结晶性能的金属氧化物负载工艺,在保证催化剂高活性同时,不影响吸附剂的吸附功能,从而产生吸附驱动催化氧化功能,具有重要应用价值。
发明内容
针对现有技术存在的问题,本发明的一个目的在于提供一种效果良好的吸附-光热催化剂的制备方法。用FeCl3活化的活性碳作为芬顿反应催化剂,催化TiO2-CeO2的过氧化前驱体在活性炭介孔内原位分解生成TiO2-CeO2纳米颗粒。TiO2具有良好的光催化性能,CeO2具有良好的热催化活性,TiO2-CeO2复合材料的界面存在光催化剂TiO2和热催化剂CeO2之间的协同作用。同时,通过活性炭对VOCs的吸附及对太阳光红外部分的热效应,实现吸附驱动光热高级氧化降解有机污染物。
