基于可见光的高活性空气净化剂及其制备方法
摘要：
本发明涉及一种基于可见光的高活性空气净化剂及其制备方法，该净化剂包括ATP、SnO2、TiO2，是以ATP为基体层、SnO2为中间过渡层、TiO2为包覆层的层状复合结构；制备方法为：首先，凹凸棒石粘土矿物经选矿、粉碎、过筛、提纯得到凹凸棒石粘土粉体ATP；然后，分别制备SnO2及TiO2溶胶；其次，ATP与SnO2进行复合，得到ATP/SnO2单一复合体；最后，再将ATP/SnO2单一复合体与TiO2进行二次复合，得高活性的ATP/SnO2/TiO2纳米复合净化剂。本发明得到的净化剂安全可靠，能有效改善日益恶化的室内外环境，减少疾病的发生，可广泛应用于家居、餐饮、医院和办公室等场所。
摘要（英）：

The invention relates to a high-activity air purificant based on visible light and a preparation method thereof. The purificant comprises ATP, SnO2 and TiO2, and is a laminated composite structure taking the ATP as a substrate layer, the SnO2 as an intermediate transition layer, and the TiO2 as a coating layer. The preparation method comprises the following steps that: firstly, an attapulgite clay mineral is produced into attapulgite clay powder ATP through ore dressing, crushing, screening and purifying; secondly, SnO2 sol and TiO2 sol are respectively prepared; thirdly, the ATP and the SnO2 are compounded to obtain an ATP/SnO2 single complex; and finally, the ATP/SnO2 single complex and the TiO2 are secondarily compounded to obtain the high-activity ATP/SnO2/TiO2 nanometer composite purificant. The purificant obtained by the invention is safe and reliable, can effectively improve deteriorated indoor and outdoor environment, reduce occurrence of diseases, and can be widely applied to households, catering, hospitals, offices and other places.
