项目摘要

With support from the Environmental Chemical Sciences Program of the NSF Division of Chemistry, Professors Ching-Hua Huang of Georgia Institute of Technology and Virender Sharma of Texas A&M University will study multi-oxidant systems that involve peroxy acids (POA) and metals, for applications in water treatment. POA, ferrate(VI) and permanganate(VII) are well-recognized oxidants, but each shows some limitations individually. The project will explore the combination of POA with high valent metal (HVM) or low valent metal (LVM) ions in a multi-oxidant system that can degrade contaminants in water treatment and activate chemical bonds in organic synthesis. This project aims to elucidate the fundamental reaction kinetics and mechanisms to maximize the application potential. Additionally, this project will enhance education and broaden participation of underrepresented groups. Example activities include teaching and recruiting minority students to participate in research though partnerships with nine minority institutions in Georgia and Texas and teaching K-12 STEM (science, technology, engineering and mathematics) teachers. The interaction of POA with either high-valent metal (HVM) (e.g., ferrate(VI) and permanganate(VII)) or low-valent metal (LVM) (e.g., Fe(II) and Mn(II)) species can significantly enhance the degradation of water contaminants. The generation of POA-based radicals and intermediate high-valent metal oxo species (e.g., Fe(V, IV)=O, Mn(VI, V, IV)=O) likely provides the much enhanced multi-oxidants conditions. The proposed “POA-Metal” system can enhance (i) the C-H bond activation of hydrocarbons, and (ii) decontamination of water. This project combines complementary laboratory experiments, kinetic modeling, and computational chemistry calculations in an effort to elucidate mechanistic details to achieve catalytic cycling of the metal as well as high efficiency in the organic oxidation. The new insights into the combined oxidants have the possibility of generating robust catalytic oxidative systems for use in both synthetic chemistry and water treatment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
在美国国家科学基金会化学部环境化学科学项目的支持下,佐治亚理工学院的黄清华教授和德克萨斯农工大学的维伦德·夏尔马教授将研究涉及过氧酸(POA)和金属的多元氧化剂体系,用于水处理。POA、高铁酸盐(VI)和高锰酸盐(VII)是公认的氧化剂,但每种都显示出各自的局限性。该项目将探索POA与高价金属(HVM)或低价金属(LVM)离子在多元氧化体系中的结合,该体系可以降解水处理中的污染物并激活有机合成中的化学键。本项目旨在阐明基本的反应动力学和机理,以最大限度地发挥其应用潜力。此外,该项目将加强教育,扩大代表性不足群体的参与。示范活动包括通过与佐治亚州和德克萨斯州的九个少数民族机构建立伙伴关系,教授和招募少数族裔学生参与研究,以及教授K-12 STEM(科学、技术、工程和数学)教师。POA与高价金属(HVM)(如高铁酸盐(VI)和高锰酸盐(VII))或低价金属(LVM)(如Fe(II)和Mn(II))的相互作用可显著增强水污染物的降解。基于POA的自由基和中间高价金属氧物种(例如,Fe(V,IV)=O,Mn(VI,V,IV)=O)的产生可能提供了大大增强的多氧化剂条件。建议的“POA-金属”体系可以增强(I)碳氢化合物的C-H键活性,以及(Ii)水的净化。该项目结合了补充的实验室实验、动力学建模和计算化学计算,努力阐明实现金属催化循环以及有机氧化的高效的机理细节。对组合氧化剂的新见解有可能产生用于合成化学和水处理的强大催化氧化系统。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
