英文摘要	a novel graphitic-nanofilament-(gnf-) supported ru-ba catalyst is prepared and used in ammonia synthesis reaction. the ru-ba/gnfs catalyst shows remarkably high activity and stability for ammonia synthesis, which can be attributed to high purity and graphitization of gnfs with unique structure. tem micrographs of the ru-ba/gnfs catalysts show that ru metal particles uniformly disperse on the outer wall of gnfs, and the particles become bigger than that before ammonia synthesis reaction after 50 h of operation at 500degreesc and 7.0 mpa, probably due to the ru crystals covered by promoter and support materials and/or sintering of ru crystals.
