To the extent that we think in a static way, it is certainly not understandable. In such a manner, dynamics yields behavior quite different from statics. When we want to prepare an iron nitride, for example, one of the most orthodox ways is to put iron in a nitrogen atmosphere under pressures higher than the dissociation pressure of the iron nitride at temperatures sufficiently high to let the nitrogen penetrate into the bulk iron. This is the way thermodynamics tells us to proceed, which requires an elaborate, expensive high-pressure apparatus, sophisticated techniques, and great efforts. However, if we flow ammonia over the iron, even under low pressures, we can easily prepare the nitride-provided the hydrogen pressure is sufficiently low. Since the nitrogen desorption rate is the determining step of the ammonia decomposition on the iron surface, the virtual pressure of nitrogen at the surface can reach an extremely high level (as is generally accepted) because, in such a dynamic system, the driving force of the ammonia decomposition reaction pushes the nitrogen into | | 出版日期 | Book 1993 | | 关键词 | catalysis; chirality; electrochemistry; metals; structure | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4899-1636-5 | | isbn_softcover | 978-1-4899-1638-9 | | isbn_ebook | 978-1-4899-1636-5Series ISSN 1574-0447 | | issn_series | 1574-0447 | | copyright | Springer Science+Business Media New York 1993 |
