Silica supported ruthenium oxide nanoparticulates as efficient catalysts for water oxidation

Pre-synthesized ruthenium dioxide nanoparticulates (RuO2 NPs) with low level of aggregation were well dispersed in mesoporous silica SBA-15. As a catalyst for water oxidation, the supported RuO2 NPs exhibit excellent catalytic activity and recyclability. The initial turnover frequency (TOF) is to date the highest among comparable RuO2 catalysts.
