Electrodeposition

Electrodeposition

Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.
Electrodeposition can...

Background:

Conventional powdery catalysts struggle with high current densities in alkaline hydrogen generation.
Slow kinetics of the Volmer step hinder large-scale alkaline hydrogen production.

Purpose of the Study:

To develop an ultrastable hydrogen evolution reaction (HER) electrode with superior performance.
To address the limitations of current catalysts for industrial-scale alkaline hydrogen generation.

Main Methods:

Preparation of freestanding surface disordered NiCu solid solution using a hydrothermal process with ammonium ion.
Electrochemical testing to evaluate HER activity and stability at high current densities.
Density functional theory (DFT) calculations to elucidate the catalytic mechanism.

Main Results:

The NiCu catalyst exhibits a unique intertwined 3D microstructure.
Achieved superior HER activity with an overpotential of 322 mV at 1000 mA cm^-2.
Demonstrated limited degradation after 110 hours of continuous operation at 1000 mA cm^-2.

Conclusions:

The disordered NiCu solid solution is an ultrastable and highly active electrode for alkaline HER.
Optimizing catalyst structure and facilitating intermediate desorption enhances industrial-scale HER performance.
Cu substitution accelerates hydroxyl desorption, improving Volmer step kinetics.
