초록

MnO2는 배터리, 촉매 및 capacitor 등의 사용으로 인하여 이의 수요는 날로 증가하고 있다. 본 연구는 sacrificial core 법을 이용하여 MnO2 중공 미세구를 제조하였다. 이때 MnO2 나노입자는 manganese acetate의 가수분해 및 축합반응에 의해 제조되었다. 실험결과 물 0.2%, manganese acetate 0.65 mM, 촉매 0.02 mM를 실온에서 반응시켜 실험을 하였을 때 일정한 모양의 MnO2 hollow microsphere를 제조할 수 있었다.

Demand for MnO2 has been increased with interest for its various applications in the fields of battery, catalyst, and capacitor. In this study, MnO2 hollow microspheres were synthesized by sacrificial core method. MnO2 nano particles were produced by the hydrolysis and condensation of manganese acetate. The stable MnO2 hollow microspheres can very well be synthesized with mixing 0.2% of water, 0.65 mM of manganese acetate, and 0.02 mM catalyst at a room temperature.

Keywords:MnO2;hollow;microsphere;sacrificial core method;coating
