Electrodeposition of Ni-Zn-S films from zinc plant filter cakes: A waste-derived electrocatalyst for alkaline hydrogen evolution

Key Points

• Alkaline hydrogen evolution efficiency improved with newly developed electrocatalyst.
• The electrocatalyst demonstrated a 20% increase in hydrogen production rates compared to existing materials.
• Electrodeposition process utilizes zinc plant filter cakes, a significant waste product, to create Ni-Zn-S films.
• This innovation supports sustainable practices by transforming waste into valuable resources.
