摘要：

Gold microband channel electrodes (30 mum in length) are used to study the reduction of ortho-bromonitrobenzene in dimethylformamide solution. An ECE mechanism is shown to operate and a rate constant of 250 s-1 for the chemical step is deduced. The ability to distinguish between ECE and DISP1 processes with the experimental protocol adopted is noted.
