The fj.J"st are easy to define : they are those in which a reduced metal is the active phase. It is thus easy to circumscribe. by exclusion, the other class namely the "non-metals". We have adopted this definition for the sake of our colleagues working on catalysis by metals, and to avoid a lengthy title like "sm‘ face pl"operties and catalysts by transi tion metal oxides. sulftdes, carbides, nitriles, etc. Defined in this manner, non-metal catalysts represented, in 1980, 84 wt. % of the industrial heterogeneous catalysts. To be more specific, this proportion corresponds to catalysts which, under the working conditions in the industrial ?lant. contain their catalytically active metallic elements in a non-reduced state. It should however be recalled that most metal catalysts are supported on oxides, which, often, repl‘esent over 90% (sometimes 99.4% in the case of the platinum reforming catalysts) of the total weight. | | 出版日期 | Book 1983 | | 关键词 | catalysis; catalyst; kinetics; metals; spectroscopy; structure | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-7160-8 | | isbn_softcover | 978-94-009-7162-2 | | isbn_ebook | 978-94-009-7160-8Series ISSN 1389-2185 | | issn_series | 1389-2185 | | copyright | D.
