A Dual-Barrel Carbon Fiber Microelectrode for Generator-Collector Experiments.

ABSTRACT: Generator-collector systems have been intrinsically related to electrochemical studies for decades, from kinetics studies to quantification processes. Herein, a new protocol for fabricating a dual carbon fiber microelectrode using a dual-barrel capillary is described. The fabrication process involves the use of inexpensive carbon fiber and requires minimal specialized equipment, except for a micropipette puller. The resulting microelectrodes exhibit a microdisc geometry, which is advantageous due to their well-defined diffusion profiles. The electrode was characterized electrochemically and through imaging experiments (scanning electron microscopy). The device was then employed in a generator-collector mode, and using [Ru-(NH3)6]-Cl3 as a redox probe in an SECM configuration, an increase i
