초록

층상 실리케이트를 주형으로 이용하여 실리케이트의 층간에 pyrolized fuel oil (PFO)를 삽입하고 열분해시킨 후 실리케이트 골격을 용출 제거함으로써 다공성 층상카본을 제조하였다. 층상카본의 입자모양은 층상실리케이트 주형과 유사한 판상 형태이며, d-spacing은 0.78~0.82 nm로 일정한 값을 나타내었다. 실리케이트와 PFO의 혼합비율과 열처리 온도, 열처리 시간에 따른 비표면적은 30~576 m2/g로 크게 다른 값을 나타내었다.

Porous layered carbon was prepared by interlayer pyrolysis of pyrolysis fuel oil (PFO) using layered silicate template and successive dissolution of template. Particle morphology was plate type with d-spacing of 0.78~0.82 nm and constant interlayer space. Specific surface area was 30~576 m2g depending upon emplate type, mixing ratios, pyrolysis temperature and pyrolysis time.

Keywords:layered carbon;kenyaite;template;pyrolyzed fuel oil;intercalation
