Synchrotron X-rays, 58 keV, were used to measure the pair distribution function on an operating fuel cell and observe the growth of catalyst particles under accelerated degradation conditions. The stability of Pt/C and PtCo/C with different initial particle sizes was monitored over 3000 potential cycles. The increase in particle size was fit to a linear trend as a function of cycles. The most stable electrocatalyst was found to be the alloyed PtCo with the larger initial particle size.","PeriodicalId":11627,"journal":{"name":"Electrochemical and Solid State Letters","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82273377","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}

Spectroscopic monitoring of surface catalysis showed that graphene crystals evolve from densely distributed nucleation points that interconnect to form large crystals covering the entire surface. Secondary nucleation was observed inside the primary graphene crystals. An effective activation energy for copper-catalyzed ethylene-based graphene synthesis was determined to be 2.46 eV, a value that suggests surface dehydrogenation of ethylene or lattice integration of graphene as the possible rate-determining step in the heterogeneous catalysis.","PeriodicalId":11627,"journal":{"name":"Electrochemical and Solid State Letters","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74355275","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}

Upon addition of oxone, the Ru removal rate increases significantly in the pH range of 1‐6. The slurry stability is poor at pH 3 and higher. At pH 2, oxone enhances the Ru removal rate even in the absence of abrasive, indicating that a soft film is formed on the Ru surface. Ru dissolution experiments show that the static etch rate is low. The Ru removal rate variation with pressure and velocity does not follow the Preston equation.","PeriodicalId":11627,"journal":{"name":"Electrochemical and Solid State Letters","volume":"100 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80321645","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}
