Surface Photochemistry and Redox Chemistry of Adsorbates on Oxide Surfaces at the Adsorbed Water Interface: Fundamental Studies of Atmospheric Significance

化学系的环境化学科学（ECS）项目将支持爱荷华大学Vicki Grassian教授的研究项目。Grassian教授和她的学生将使用不同的光谱工具、同位素标签、显微镜和计算进行详细的机制研究，以更清楚地了解具有大气意义的化学反应。Grassian教授和她的学生将研究在不同表面和不同化学环境下吸附发色团的表面光化学，特别是硝酸盐离子。他们还将研究人为金属氧化物粉尘的表面化学、光化学和氧化还原化学。这项研究具有潜在的变革性，因为它可能改变我们对大气中矿物粉尘气溶胶的化学性质及其对气候的影响的看法。该项目将为渴望在环境科学前沿工作的学生提供良好的教育机会，包括一些来自代表性不足的群体的学生。

The Environmental Chemical Sciences (ECS) program of the Division of Chemistry will support the research program of Prof. Vicki Grassian of the University of Iowa. Prof. Grassian and her students will carry out detailed mechanistic studies using different spectroscopic tools, isotope labels, microscopy and calculations to provide a clearer understanding of chemical reactions that are of atmospheric significance. Prof. Grassian and her students will study the surface photochemistry of adsorbed chromophores, in particular the nitrate ion, on different surfaces and in different chemical environments. They will also study the surface chemistry, photochemistry and redox chemistry of anthropogenic metal oxide dusts. The study is potentially transformative since it could change the way we think about the chemistry of mineral dust aerosol in the atmosphere and its impact on our climate. The project will provide excellent educational opportunities for students, including some from under represented groups, desiring to work at the forefront of environmental science.
