摘要

随着物质生活的不断提高

甲醛成为了室内空气污染的主要物质

对于室内空气净化过程

去除甲醛技术变得尤为重要. 利用条件温和、过程简单的水浴法使二氧化锰(MnO

)原位负载到聚对苯二甲酸乙二醇酯(PET)制成的无纺织物上

制备出MnO

/PET整体式催化剂. 合成的MnO

/PET复合物通过扫描电子显微镜(SEM)、X射线衍射(XRD)、比表面积测试(BET)进行表征分析

并在手套箱中模仿室内环境进行甲醛去除测试以及催化剂寿命测试. 结果表明: 整体式催化剂中的锰氧化物为水钠锰矿型二氧化锰

并均匀、牢固负载在无纺布上. 由于其有较大的比表面积

在甲醛去除能力方面展示出了优良的性能

在甲醛初始质量浓度为2.84 mg/m

的氛围测试中经过6 h

最后使甲醛质量浓度降低至0.33 mg/m

甲醛去除率达到88.29%. 提供了一种高效的去除甲醛的催化剂合成方法

这种整体式催化剂为室内甲醛催化净化拓展了新的思路.

Abstract

With the continuous improvement of material life

formaldehyde has become the main substance of indoor air pollution. For indoor air purification

the removal of formaldehyde becomes particularly important. Manganese dioxide (MnO

) was in-situ loaded onto non-woven fabric made of polyethylene terephthalate (PET) by water bath method

which has mild reaction conditions and simple processing. The synthesized MnO

/PET composites were characterized by scanning electron microscope (SEM)

diffraction of X-rays (XRD) and specific surface area test (BET)

imitating the indoor environ

ment to make the initial concentration of 2.84 mg/m

after 6 h

and making the concentration of the formaldehyde to 0.33 mg/m

with the removal rate of formaldehyde reaching 88.29%. This study provides an efficient method for the synthesis of formaldehyde oxidation catalyst

which provides a new idea for indoor formaldehyde catalysis.
