This type of catalyst is well studied and repeatedly reviewed [1–3]. Its high effectiveness can be interpreted within a dual-site concept according to which hydrocarbon adsorbs on an active site associated with one of the metal oxide components while oxygen adsorbs on an active site associated with another metal oxide component. For instance, the authors [4, 5] assume a bismuth center to be responsible for the hydrocarbon conversion to an allylic species which then reacts further at a molybdenum site to produce aldehyde.","PeriodicalId":50986,"journal":{"name":"Catalysis Reviews-Science and Engineering","volume":"27 1","pages":"1-23"},"PeriodicalIF":10.9,"publicationDate":"1994-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74790581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The targets established by the CAA were directed to overcoming environmental problems by reducing the ground-level ozone-forming and carbon monoxide emissions from vehicles, as well as toxic hydrocarbons and SO, and NO, emissions in auto exhausts. In order to accomplish this, gasolines had to move in the following direction: Reduce volatility: that is, lower Reid vapor pressure (RVP), especially during summer months, in order to reduce ozone levels. This can be achieved by removing butanes and even C, from the gasoline. Limitations in the aromatic content, with special emphasis on benzene.

Attention is given to the threeway catalyst system which simultaneously promotes the reduction of nitrogen oxides and the oxidation of carbon monoxide and hydrocarbons. These systems have been used on most passenger cars in the United States since 1982. Prior to 1980, emission control catalysts were oxidation catalysts, and reduction in exhaust nitric oxide was achieved using engine modifications (i.e., exhaust gas recirculation). This review focuses on catalytic control of NO, for gasoline-fueled vehicles (not diesels and alternate fuels) and primarily on developments reported since 1982. The term NO, refers to both NO and NOz. The reader is referred to an earlier publication by the author for a general review of automobile catalytic converters [1] and to a review by Egelhoff [2] on the nitric oxide literature through 1980.

Such planar deposits have been employed in the past to study the physical [3–11] and chemical [12–20] properties of mesoscopic metal aggregates. In these studies, the emphasis has usually been placed on pointing out the differences in particle properties with respect to the bulk properties of the same material. Although it has often been found that the electronic properties reach bulk values at surprisingly small cluster sizes of about 30 to 50 atoms, it has also been observed that the chemical properties can change over a much wider particle size range [21] for structure-sensitive reactions [22].
