Our plan and strategy encompasses designing mixed metal oxide structures using bottom-up surface chemical approaches by functionalizing model surfaces and growing tailored metal oxide heterostructures at different reaction conditions. These new materials will then be used to study reactions and kinetics of gas phase and liquid phase pollutants under conditions that mimic the environment, such as pH, heat and light.

The studies proposed here will show how new bottom-up approaches to material design help create new architectures that model heterogeneous catalysts and minerals in the environment. New architectures can be used as model platforms to study environmentally relevant reactions that can help us determine the effects of light adsorption, pollution reactions and catalytic reactions using modern surface science.

Specific aims:

bulletpointTo design and characterize metal-oxide architectures on various substrates

bulletpointTo discover new catalytic reactions and pollutant degradation on heterogeneous metal oxide materials

bulletpointTo quantify the reactivity of pollutants from both the gas and liquid phase on supported metal oxide materials under model (UHV) and real (high pressure) conditions

This will determine the surface chemistry of model and real metal oxide materials that will help us understand fundamental reactions affecting energy challenges, climate change, and human health. Heterogeneous materials will be designed and tailored to have desirable physical and chemical properties through understanding their fundamental reactions with different metal oxides. The outcomes of the studies will elucidate the catalytic and environmental implications.
