From brew to clean fuel: harnessing distillery wastewater for electrolysis H2 generation using nano scale nickle selenide water oxidation catalysts

November 2023

This study introduces an innovative method to generate green hydrogen from distillery industry wastewater. By using solvothermally derived Ni2Se3 nanoparticles as the anodic material, this method demonstrates higher current density and hydrogen gas evolution compared to conventional freshwater electrolyte, while also effectively treating the acetic acid present in the distillery wastewater. The utilisation of distillery wastewater as working electrolyte indicates potential for sustainable green hydrogen production and reduces the stress on freshwater demand. However, challenges, including aggressive bubbling at the cathode affected hydrogen evolution rates, require further investigation. Overall, this approach shows a potential solution for simultaneous wastewater treatment and hydrogen production, offering a path towards a more resource-efficient future.
