摘要
A method for imaging local electrochemical current density uses light scattered from probe particles proximate to an electrode. A 5.5 mu m particle near a working electrode (WE) scattered light more intensely or less intensely as a function of local current density. The light intensity correlated with the measured current. A current density of 1 A/m(2) was easily resolved. Fair agreement between the measured superficial current density and current density calculated from the light scattering intensity was achieved. The results demonstrate a method for imaging spatially varying electrochemical reaction rates with high resolution.
