绿色过氧化氢有望“即产即用”

Group 1 - The research team at Tianjin University has developed a high-performance electrocatalyst for the efficient synthesis of green hydrogen peroxide, which is expected to achieve "on-demand" production [1][2] - Hydrogen peroxide is a crucial oxidant and disinfectant with a projected global demand of 6 million tons by 2024, but 95% of its current production relies on the energy-intensive anthraquinone process, posing safety and environmental risks [1][2] - The new electrocatalytic synthesis method utilizes oxygen and water at ambient conditions, addressing the challenges of low activity, poor selectivity, and insufficient stability of traditional catalysts in neutral and alkaline environments [1][2] Group 2 - The developed nickel-based metal-organic framework material features a unique layered structure that forms "interlayer hydrogen bonds," enhancing the catalyst's performance for electrosynthesis of hydrogen peroxide [2] - This innovative approach allows for precise control of catalytic reactions through non-coordinative structural adjustments, offering a new strategy for the development of novel electrocatalytic materials applicable to various chemical reaction systems [2] - Testing indicates that the catalyst significantly outperforms similar products in producing hydrogen peroxide, achieving a concentration of 1% in artificial seawater and 3% in alkaline solutions, meeting practical standards for pollutant degradation and sterilization [2] Group 3 - The new catalyst addresses the high energy consumption and pollution issues associated with traditional production methods, demonstrating good applicability in neutral, alkaline, and complex water environments [3] - The research team is currently optimizing the production process to transition the technology from laboratory to industrial production, aiming to replace traditional high-pollution methods and contribute to green chemical goals [3]
