Description
技术领域
本发明属于环境净化材料领域,具体涉及一种制备钛镓沸石型光催化材料的方法。
背景技术
沸石是沸石族矿物的总称,是一种含水的碱金属或碱土金属的铝硅酸矿物。按沸石矿物特征分为架状、片状、纤维状及未分类四种,按孔道体系特征分为一维、二维、三维体系。天然沸石都由硅氧四面体和铝氧四面体组成。天然沸石是一种新兴材料,被广泛应用于工业、农业、国防等部门,并且它的用途还在不断地开拓。沸石被用作离子交换剂、吸附分离剂、干燥剂、催化剂、水泥混合材料。沸石骨架结构中存在孔道和空腔,从而具有很大的比表面积,是一类高效吸附剂,但沸石不具备光催化降解有机污染物的活性。
光催化净化技术可以在光的作用下使环境中的有机污染物分解,从而达到治理污染的目的,已在各种污染治理领域获得广泛应用。大气、水和固体废物中的有机污染物具有不同的分子尺寸,对光催化材料的孔隙结构和尺寸具有特定要求。沸石型光催化材料不仅具有较强的吸附能力,还能在光照条件下降解环境中的有机污染物。

1.2 将烧瓶置于65℃恒温水浴中,回流70 min;
1.3 在烧瓶中加入160~180 mL去离子水,继续在65℃恒温水浴中回流70 min,制得钛镓醇盐固液混合物。
步骤2:热反应生长钛镓沸石
2.1 将烧瓶中固液混合物移入不锈钢反应釜中,控制反应温度190~220℃,反应体系压力2~2.5 MPa,反应时间80~100 h;
2.2 反应结束后,将固液混合产物过滤,用去离子水清洗滤饼;
步骤3:孔道和空腔成型
3.1将滤饼放入1L两口圆底烧瓶,并加入500 mL 0.5mol/L盐酸溶液,安装测温热电偶和球形冷凝管,冷凝管通入自来水进行冷却;
3.2将烧瓶置于90℃恒温水浴中,回流200 min;
3.3将固液混合产物过滤,用去离子水清洗滤饼;
3.4 将滤饼在210℃恒温电热干燥箱中放置24h;
3.5 将干燥后的固体产物在860~1050℃煅烧3~6h,冷却后在瓷研钵中研磨成粒径小于10 μm的粉末,即制得钛镓沸石型光催化材料。
