The study discusses the development of an innovative biochar sacrificial anode to improve hydrogen production efficiency through carbon-assisted water electrolysis. By addressing mass transfer limitations, the sacrificial anode demonstrated enhanced performance in hydrogen production. The research focused on the impact of oxidation-induced N-doped pinewood on persistent free radicals, highlighting improved electrochemical properties and durability. Results showed that the anode potential was significantly lower compared to traditional Pt anodes, with minimal gas byproducts, maintaining high hydrogen production efficiency. The oxidation process led to the transformation of free radicals, promoting efficient hydrogen evolution. The study emphasizes the role of biochar in achieving green H2 production from biomass sources, offering a cost-effective and sustainable alternative. Overall, the findings suggest that the biochar sacrificial anode design could revolutionize hydrogen production processes by improving energy efficiency and reducing environmental impact.
