Study of deactivation mechanism over SiO2 supported Ni catalysts for direct internal reforming in molten carbonate fuel cell |
| 초록 |
A direct internal reforming (DIR) reaction for a molten carbonate fuel cell (MCFC) was carried out using SiO2 supported catalysts, which are known to be a highly stable. The SiO2 supported Ni catalysts rapidly deactivated in DIR-MCFC. To elucidate the mechanism of the catalyst deactivation, various characteristic analyses (BET, H2-chemisorption, FT-IR, and SEM) of fresh and used catalysts were employed. It was found that the SiO2 species changed to Si(OH)4 in the presence of both H2O and K. This transformation caused a significant decrease in Ni dispersion and BET surface area resulting in the deactivation of the catalyst. |
