中文摘要：

以高锰酸钾和双氧水为原料,采用沉淀法制备了介孔二氧化锰催化剂,利用X射线衍射（XRD）、扫描电子显微镜（SEM）、比表面积（BET）和傅里叶变换红外光谱（FTIR）表征二氧化锰的形态结构。以介孔二氧化锰为催化剂,在室温、常压、无光照条件下对甲醛气体进行了催化氧化试验。试验结果表明,二氧化锰具有良好的催化氧化活性,能将甲醛催化氧化成二氧化碳和水,4h甲醛有效净化率达到99%。

英文摘要：

The mesoporous manganese dioxides were synthesized by precipitation of potassium perman- ganate and hydrogen peroxide. The morphology structure of manganese dioxides was characterized by X-ray diffraction （XRD）, scanning electron microscope （SEM）, brunauer emmett teller （BET） and Fourier transform in- frared spectroscopy （FTIR）. Mesoporous manganese dioxide was used as catalyst of formaldehyde catalytic oxi- dation tests under normal temperature and pressure and matt environment. The catalytic oxidation activity of manganese dioxides was confirmed by the degradation test of formaldehyde. The results showed that after 4 h, the formaldehyde could be oxidized to carbon dioxide and water, and the formaldehyde purification efficiency was 99%.
