Abstract

Carbon nano sphere(CNS) and nano bowl of carbon(NBC) containing 1.0 wt% copper were prepared by impregnation method and their catalytic activity was compared in the phenol hydroxylation with hydrogen peroxide in the presence of water and acetonitrile as a solvent, respectively. Cu content of catalysts was determined by EDS, and BET, pore volume, pore size and pore size distribution were compared. For both catalysts, phenol conversion, $H_2O_2$ efficiency and yield of catechol and hydroquinone were higher in the presence of water as a solvent than those in the presence of actonitrile. And catalytic activity such as phenol conversion and $H_2O_2$ efficiency of 1.0 Cu/CNS is about two times higher than that of 1.0 Cu/NBC in water solvent.

나노구조를 갖는 중공구형(CNS) 및 중공반구형(NBC) 다공성 탄소 담체에 각각 약 1.0 wt%의 구리를 담지시켜 두 종류의 촉매를 제조하였고 과산화수소수에 의한 페놀의 수산화 반응에서 촉매의 성능을 두 종류의 서로 다른 용매(물, 아세토니트릴)에 대하여 비교 분석하였다. 촉매에 담지된 구리의 양은 EDS 분석으로 확인하였고 비표면적, 기공 부피, 기공 분포도 등을 비교 분석하였다. 두 종류의 촉매에서 모두 아세토니트릴보다 물에서 더 높은 전환율과 과산화수소 유효도 및 카테콜과 하이드로퀴논의 생성율을 얻을 수 있었고, 물을 용매로 사용했을 때 1.0 Cu/CNS 촉매가 1.0 Cu/NBC 촉매보다 50% 이상의 전환율과 과산화수소 유효도를 보였다.
