摘要：

通过500℃焙烧卵状MnCO₃前驱体，制得了一种高效降解亚甲基蓝的卵状ε-MnO₂催化剂.采用扫描电子显微镜、X射线衍射分析仪、紫外可见分光光度计、比表面积测定仪对材料进行了测试.结果显示，卵状ε-MnO₂催化剂具有很高的比表面积，为88 m²/g.将制得的卵状ε-MnO₂材料应用于亚甲基蓝的降解，在H₂O₂存在下，卵状ε-MnO₂对亚甲基蓝的脱色率高达92%，表现出在室温下去除亚甲基蓝的优越能力.

Abstract:

In this paper, through calcining the ellipsoid-like MnCO₃precursors at 500°C, the ellipsoid-like ε-MnO₂ catalysts with an excellent property to decompose methylene blue can be obtained. ε-MnO₂is measured by SEM, XRD, UV-Vis and BET. The results show that the ellipsoid-like ε-MnO₂catalysts possess a high surface area of ca.88 m²/g. The obtained ellipsoid-like ε-MnO₂ materials are used as catalysts to decompose methylene blue in the present property of H₂O₂.And the ellipsoid-like ε-MnO₂ can remove about 92% of methylene blue, which shows excellent property to remove methylene blue at room temperature. This shows that ellipsoid-like ε-MnO₂ is a highly efficient catalyst removal of methylene blue.

Key words: epsilon-manganese oxide (ε-MnO₂); ellipsoid-like; catalytic degradation; methylene blue
