Abstract

Reduction and nanoparticle nucleation of Cu2+ by decamethylferrocene was
studied with cyclic and square-wave voltammetry at a microscale liquid–liquid
interface established at the tip of a micropipette. With square-wave voltammetry, two reduction steps could be distinguished as two separate current waves.
Comparing the experimental results of cyclic voltammetry with finite element
method simulations, particle growth could be observed as an increasing limiting
current. Furthermore, kinetic parameters could be estimated with square-wave
voltammetry simulations following Butler-Volmer kinetics.
