Structure and Activity of Ni- and Sb-doped SnO₂ Ozone Anodes

摘要

Data are presented on the effect of the loading of Ni/Sb-SnO₂ on the physical, structural and electrochemical characteristics of this highly active ozone electrocatalyst with the aim of understanding its catalytic activity. The data strongly suggest that, despite the ‘cracked earth’ morphology of the catalysts, the walls of the fissures do not contribute to the observed electroactivity, both in terms of ferrocyanide oxidation or O₃ and O₂ evolution. In addition, the data indicate that there is a surface enrichment of Ni, and hence active sites, with increasing loading.View full textDownload full textKeywordsOzone, Electrochemical Ozone Generation, Anodes, ElectrodesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01919512.2012.639687
