초록
카본나노튜브에 담지된 몰리브데늄 카바이드 촉매를 다양한 제조 조건을 통해 제조하여 촉매특성을 분석하였고, 메탄올의 전기화학적 산화반응을 통해 촉매의 활성을 비교하였다. 촉매로써 전이금속의 낮은 활성을 극복하기 위한 방안으로 카본나노튜브를 지지체로 사용하였으며 전구체의 양 및 종류, 지지체의 산처리 방법, 탄화공정 온도조건 등을 변화하여 촉매를 제조하였다. 제조된 촉매는 ICP-AES, XRD, TEM을 통하여 촉매의 특성을 분석하였고, 메탄올의 전기화학적 산화반응을 통해 촉매의 활성을 비교하였다. 몰리브데늄 카바이드 촉매(Mo2C/CNT)의 다양한 제조방법으로 입자크기와 담지량을 변화시킬 수 있었으며, 입자의 크기와 담지량의 변화에 따른 전기화학적 산화반응의 특성을 설명할 수 있었다.
Carbon nanotube supported molybdenum carbide catalysts were prepared as a function of various preparation conditions and characterized, and their catalytic activities were compared through electrochemical oxidation of methanol. To overcome the low activity of a transition metal catalyst, carbon nanotube was used as a support, and the amount and the kind of precursors, acid treatment method, and carburization temperature were varied for the catalyst preparation. ICP-AES, XRD and TEM were used for the catalyst characterization. Based on the various preparation methods of carbon nanotube supported molybdenum carbide catalysts (Mo2C/CNT), the size and the amount of supported catalysts could be controlled, and their effects on the electrochemical oxidation could be explained.
