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:

Controlling selectivity in electrocatalytic CO2 reduction (eCO2R) to valuable products is challenging.
Many electrocatalysts rely on non-renewable metals, hindering sustainable applications.

Purpose of the Study:

To prepare bimetallic copper-lead (CuPb) electrocatalysts from industrial metallurgical waste.
To tune the composition of CuPb electrocatalysts for enhanced eCO2R selectivity.
To investigate the synergistic effects of Cu and Pb in eCO2R.

Main Methods:

Extraction of metal ions from metallurgical waste using ammonium chloride treatment.
Fabrication of tunable CuPb electrocatalysts via electrodeposition.
Characterization using X-ray spectroscopy and in situ Raman spectroscopy.
Electrocatalytic CO2 reduction performance evaluation.

Main Results:

CuPb electrocatalysts with tunable compositions (Cu_xPb_y) were successfully prepared from waste.
A volcano-shape relationship was observed between Cu:Pb ratio and selectivity for CO production.
The optimal Cu9.00Pb1.00 catalyst achieved a fourfold increase in CO Faradaic efficiency compared to pure Cu.
Synergistic effects between Cu and Pb improved the reducibility of metal domains and enhanced CO selectivity.

Conclusions:

Valorization of metallurgical waste provides a sustainable source for effective electrocatalysts.
Tuning the elemental ratio in bimetallic CuPb systems is crucial for optimizing eCO2R selectivity.
This work offers a strategy for designing selective electrocatalysts for CO2 reduction from waste materials.
