Linking Molecular Scale Surface Speciation to Interfacial Fe Redox Chemistry

化学系的环境化学科学(ECS)计划将支持爱荷华大学的Michelle Scherer教授和Vicki Grassian教授以及Coe学院的Martin St.Clair教授的合作研究项目。合作研究人员和他们的学生将研究有机物在氧化铁矿物表面的吸附动力学。这项研究将利用先进的光谱方法和计算建模方法来审问这一复杂而重要的环境界面。先进的表面光谱方法将被用来表征在纳米和微米级针铁矿和赤铁矿颗粒上形成的吸附表面络合物的分子水平细节。这项研究可以大大提高我们在分子水平上对环境中无处不在的氧化铁表面氧化还原过程的理解。这项工作的发现将为社会提供对分子尺度反应的洞察，这些反应对保护国家水体的健康非常重要。这项研究将为爱荷华大学和COE学院的研究生和本科生提供从事环境化学科学尖端研究项目的绝佳机会。

The Environmental chemical Sciences (ECS) program of the Division of Chemistry will support the collaborative research project of Prof. Michelle Scherer and Prof. Vicki Grassian of the University of Iowa, and Prof. Martin St. Clair of Coe College. The collaborating investigators and their students will study sorption dynamics of organic substances on iron oxide mineral surfaces. The study will make use of advanced spectroscopic methods and computational modeling methods to interrogate this complex and important environmental interface. Advanced surface spectroscopic methods will be used to characterize the molecular level details of the adsorbed surface complexes formed on nanoscale and microscale goethite and hematite particles. The study could significantly increase our understanding at the molecular level of redox processes on the environmentally ubiquitous iron oxide surfaces. Findings from this work will benefit society by providing insights into molecular scale reactions that are important in protecting the health of the Nation's water bodies. The study will provide excellent opportunities to graduate and undergraduate students at the University of Iowa and Coe College to work on a cutting edge research project in environmental chemical sciences.
