Comparatively high platinum dispersion and low average particle size caused by impregnation of the zeolite with ethanolic H<sub>2</sub>PtCl<sub>6</sub> solution lead to a close vicinity of metal and acid sites which is accompanied by an increased electrophilicity of the metal. Such a catalyst posesses a higher deactivation rate than those with more bulky platinum. The rapid deactivation is effected by a higher stability of the chemisorption complex metal-ethylene and by favouring of consecutive reactions of olefinic intermediates towards coke information.</p></div>","PeriodicalId":8091,"journal":{"name":"Applied Catalysis","volume":"78 2","pages":"Pages 257-264"},"PeriodicalIF":0.0,"publicationDate":"1991-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0166-9834(91)80110-I","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90029996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been established that after leaching of the alloy with alkali solution copper particles are formed, covered by a hydroxycarbonate film containing mainly a hydrotalcite like phase. Most probably this system is the precursor of the active sites, similar to the WGS catalysts obtained by coprecipitation. The Raney type catalysts manifested catalytic activity by an order of magnitude higher than that of the conventional coprecipitated catalysts. This could be explained by the formation of a complex catalytic system, containing a “polyelectrode” of a redox galvanic couple of copper ions, closed via the metal phase.</p></div>","PeriodicalId":8091,"journal":{"name":"Applied Catalysis","volume":"78 2","pages":"Pages 199-211"},"PeriodicalIF":0.0,"publicationDate":"1991-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0166-9834(91)80106-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90030005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
