Photoelectrochemical reduction of p-bromonitrobenzene: Mechanistic discrimination via channel microband array voltammetry

Abstract:

Two dimensional voltammetry using an array of channel microband electrodes varying in size from ca. 2 mm to under 1 micron in length, has been used to study the photoreduction of p-bromonitrobenzene. In the dark p-bromonitrobenzene is reduced al - 1.09 V (vs. SCE). On irradiation with strong white light significant photocurrents flowed which were recorded at flow rates from 2 x 10-3 cm3 s-1 to ca. 0.3 cm3 s-1 at various electrode sizes. Mechanistic analysis of these steady-state measurements ...
