昇温脱離法を用いた金属触媒を含む規則性メソポーラスカーボンの炭素化過程の観察

Temperature-programmed desorption measurements are very useful in an evaluation of the carbonization/graphitization of carbon precursors and the reduction of transition metal species. Here, the catalytic carbonization/graphitization behaviors of furfuryl alcohol polymer in the pores of Ni- or Co-loaded MCM-48 mesoporous silica was investigated. CH₄ can reduce Ni(II) to Ni(0) at 600 °C, and the metallic Ni can then act as a catalyst for the formation of a graphitic structure within the mesopores at 1000 °C. Co(II) species can be reduced by CO at 400 °C, and the metallic Co acts as a catalyst for Boudouard reaction, steam reforming and dry reforming of CH₄, and partial graphitization up to 900 °C.
