초록
본 연구에서는 Ni metal foam 플레이트의 수증기 개질반응 및 표면 특성을 조사하였다. 전처리를 통하여 Ni의 산화상태를 변화시킬 수 있었으며, 활성 site로서 표면에 노출된 metallic Ni 종은 수증기 개질 반응활성에 중요한 역할을 한다. 또한 Ni metal foam 플레이트의 기공제어 및 촉매 기능을 부여하기 위하여 Ni metal foam 플레이트와 Ni-YSZ 촉매를 혼합하여 다공성 촉매 분리막을 제조하였다. SEM 분석 결과 metal foam 플레이트의 기공을 제어할 수 있었으며, 표면에 Ni-YSZ 촉매는 고르게 잘 분포되어 있었다. Ni 기반 다공성 촉매 분리막은 공간속도에 상관없이 상용촉매와 유사한 수증기 개질 활성을 가진다.
In this study, steam reforming reaction and surface characteristics of Ni metal foam plate were investigated. Valence state of Ni could be changed by pretreatment, and metallic Ni species exposed on surface as a active site play important role in steam reforming reaction. Porous catalytic membrane also was prepared by mixing of Ni metal foam plate and Ni-YSZ catalyst
to control the pore size and assign the catalytic function in Ni metal foam plate. In SEM analysis results, Pore size of Ni metal foam plate could be controlled and Ni-YSZ catalyst well dispersed on surface. Ni based porous catalytic membrane had a similar steam reforming activity regardless of space velocity.
