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 O-3 and O-2 evolution. In addition, the data indicate that there is a surface enrichment of Ni, and hence active sites, with increasing loading.
