제목 Characteristics of Sr0.92Y0.08Ti0.88V0.12Ni0.10O3-δ perovskite catalysts as Solid Oxide Fuel cell anode for methane dry reforming
초록 Sr0.92Y0.08Ti0.88V0.12Ni0.10O3-δ (SYTVN) with perovskite structure was studied as an alternative anode matrial for utilizing internal dry reforming of CH4 (IDRM). The SYTVN exhibited excellent characteristics as IDRM catalysts. 10 mol.% of Ni was non-stoichiometrically doped in SYTV (Sr0.92Y0.08Ti0.88V0.12O3-δ) phase to improve the IDRM catalytic performance. The exsolution of bulk Ni phase was confirmed by XRD analysis. In H2-TPR, the reduction peak showed at 400 ℃ and confirmed the metal Ni phase. The CH4 conversion of the SYTVN showed 100% in comparison to SYTV which showed 80%. The H2 selectivity was similar property with Ni/YSZ. Moreover, the carbon formation was 0.886 % in SYTVN and 14.71 % in Ni/YSZ sample. The electrochemical properties were also investigated in impedance analysis, and IV-characteristics, to feasibility as SOFC (Solid Oxide Fuel cell) anode.
