摘要

Nano-crystalline Sm_0.2Ce_0.8O_1.9 (SDC), Gd_0.2Ce_0.8O_1.9 (GDC), La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ (LSCF) and NiO (65 wt.%)-GDC powders for applications in solid-oxide fuel cells were synthesized by employing cotton fibers as the micro-bioreactor. As compared with the conventional glycine-nitrate (GN) combustion method, this novel process allows the preparation process to be more environmental-friendly. Furthermore, the particle size of obtained powders could be smaller, attributing to the blocking effect of cellulose on suppressing the particle contact during synthesis. By this innovative method, SDC powder with a particle size as small as ∼10 nm, was obtained, which can be easily sintered to dense electrolytes at 1350 °C. The process is also capable for large-scale synthesis.
