摘要：

Bis(acetylacetonato) oxovanadium(IV) was immobilized on a self-assembled 4-(pyridine-4'-amido) thiophenol modified gold electrode. The modified electrode showed excellent electrocatalytic activity towards water oxidation at neutral pH. The turnover frequency of the catalyst for water oxidation was 0.64 s(-1) at an overpotential of similar to 284 mV (at J = 3.82 mA cm(-2)).
