Hydrogen peroxide, a key industrial chemical, is traditionally produced through methods with drawbacks like high energy usage and environmental pollution. A team of South Korean researchers led by Dr. Jong Min Kim from KIST developed a groundbreaking mesoporous carbon catalyst to address these issues. By introducing mesopores into the carbon catalyst, they achieved efficient hydrogen peroxide production even in air supply environments with low oxygen concentrations and neutral electrolytes. The new catalyst, boron-doped carbon with mesopores of about 20 nanometers, displayed excellent catalytic activity in neutral electrolyte environments, overcoming previous limitations. This innovation allows for hydrogen peroxide production efficiencies exceeding 80% under near-commercial conditions, with concentrations surpassing medical standards. The research, supported by the Ministry of Science and ICT, was published in Advanced Materials, showcasing the significant advancement in hydrogen peroxide production technology. Dr. Jong Min Kim highlighted the practicality and industrial potential of this eco-friendly catalyst, emphasizing its role in accelerating industrialization and promoting greener practices. This development marks a significant step towards more sustainable and efficient production processes in industries such as medical, chemical, and semiconductor.
