The Korea Institute of Science and Technology (KIST) has collaborated with Hanyang University and Pusan National University to create a carbon-based catalyst that achieves over 95% selectivity in the electrochemical production of hydrogen peroxide (H2O2) from lignin. This biomass, often discarded in the timber and paper industries, is now being utilized as a precursor in electrocatalysis, addressing both waste management and sustainable chemical production.
The research, led by Dr. Lee Young Jun, demonstrates that the catalyst enhances the efficiency of the oxygen reduction reaction, crucial for H2O2 generation. The study indicates that high selectivity reduces energy losses and downstream purification needs, optimizing practical applications.
The findings support the potential for decentralized production systems at biomass processing facilities, aligning with circular economy goals. Future work will focus on scaling the catalyst synthesis and integrating it into industrial applications, with environmental assessments highlighting significant reductions in greenhouse gas emissions through renewable feedstocks.
