“分子钥匙”实现过氧化氢“即产即用”

Core Insights - The research team at Tianjin University has developed a high-performance electrocatalyst for the efficient synthesis of green hydrogen peroxide (H2O2), aiming for an "on-demand" production model [1][2] - The global demand for hydrogen peroxide is projected to reach 6 million tons by 2024, with 95% of current production relying on the energy-intensive anthraquinone process, which poses safety and environmental risks [1] Group 1: Research Breakthrough - The team designed a nickel-based metal-organic framework material (Ni-BTA) that utilizes unique interlayer hydrogen bonding to enhance catalytic activity for H2O2 synthesis [1][2] - This innovative "non-coordinative structural regulation" strategy allows for precise control over catalytic reactions, differing from traditional catalysts that rely on metal center electronic structures [2] Group 2: Performance and Applications - The new catalyst demonstrates significantly higher H2O2 production rates in neutral and alkaline environments compared to similar products, achieving a concentration of 1% in artificial seawater and 3% in alkaline solutions [2] - The catalyst can effectively eliminate 100% of pathogenic bacteria, such as E. coli, in physiological saline within 30 minutes and rapidly degrade toxic organic dyes, meeting practical standards for pollution degradation and disinfection [2] Group 3: Future Prospects - The research team is accelerating the industrialization process of this technology, aiming to replace traditional high-pollution methods and provide a "green" solution for medical disinfection and wastewater treatment [2]
