Original Kurzfassung:
The electrocatalytic behaviour of a thermally evaporated Cu?Ni thin
film combinatorial library was investigated by screening the entire compositional spread in alkaline solution using
flow-type scanning droplet cell microscopy. Crystallographic properties and surface microstructure were investigated
using XRD and SEM. The obtained Cu?Ni thin film alloys (1?13at.% Ni) showed suitability for being used in formaldehyde
detection. The electrochemical performance of the thin film electrodes was investigated by cyclic voltammetric and
chronoamperometric measurements. The highest electrocatalytic effect was found for Cu-6.9at.% Ni. The concept of a
formaldehyde sensor using Cu-6.9at.% Ni was tested. The identified alloy showed good performance for formaldehyde
detection in a wide linear range (3?200mM), high reproducibility (relative standard deviation 6%), longterm stability
and sensitivity to formaldehyde oxidation.
