Galvanic and bipolar cells as probes of electroless deposition: The Cu–dimethylamine borane system

Galvanic and bipolar cells were used to demonstrate the complexity of electroless deposition reactions. The separation of the half-reactions, and the ability to control the potential, demonstrate the effect of the substrate and the interdependence of the anodic and cathodic processes. The effect of...

Description
Summary:Galvanic and bipolar cells were used to demonstrate the complexity of electroless deposition reactions. The separation of the half-reactions, and the ability to control the potential, demonstrate the effect of the substrate and the interdependence of the anodic and cathodic processes. The effect of applied potential, substrate and temperature on Cu electroless deposition was studied, using dimethylamine borane as reducing agent. •Separation of half-reactions of Cu electroless deposition leads to slower kinetics.•Slower kinetics are due to changes in cell potential generated by surface effects.•Cu deposition is more heavily influenced by temperature than the anodic reaction.
