摘要：

Stable electroactive mixed films of osmium oxide/hexachloroplatinate, osmium oxide and platinum have been deposited on different electrode materials by cycling the electrode potential repetitively in solution containing Os3+ and PtCl62-. The film growth of was monitored by using cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM). The cyclic voltammetric features of modified electrode in Os3+ solution resembles that of surface wave, and involves ions-exchange With Os3+ ions present in the solution. Based oil the SEM results the modifier was considered as one-dimensional, mixed-valent polymeric film, and stabilized by Os3+/2+, counter ions. Finally, the electrocatalytic activity of the modified electrode was examined toward reduction of NAD(+), chloroacetic acids and nitrous oxide.
