摘要：
Perovskite-type oxides BaCe0.90Sm0.10O3-delta (BCS) and BaCe0.80Gd0.10Sm0.10O3-delta (BCGS) were synthesized by the sol-gel method and characterized by thermal analysis (TG-DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Using the sintered samples as solid electrolytes and silver-palladium alloy as electrodes, ammonia was synthesized from nitrogen and hydrogen at atmospheric pressure in a solid-state proton-conducting cell reactor. The maximum rate of production of ammonia was 5.82 x 10(-9) mol s(-1) cm(-2). (C) 2007 NIMS and Elsevier Ltd. All rights reserved.
