Aluminium-based Electrodes for Green Hydrogen Production through Electrolysis and Hydrolysis: A Review

Strategic Insights -

Researchers from Tshwane University of Technology have conducted a study on the development and characterization of aluminium (Al)-based composite electrodes for clean hydrogen production through hydrolysis and water electrolysis. The study aims to identify the challenges associated with Al-based materials and provide recommendations for future improvement. The researchers found that the incorporation of active additives, such as h-BN and MoS2, in Al-based composites significantly improved the rate of hydrogen evolution and gas conversion yield. However, they also noted that Al-based electrodes suffer from low current density and poor electrochemical properties, resulting in long induction times and high overpotentials.
