1. Role of specific reactive sites on silicon nitride surface in catalysis of isomerization and addition reactions
A. V. Teplyakov, Department of Chemisty and Biochemisty, University of Delaware
Si(100)-2x1 single crystal surface provides perfect model system with selectively prepared –NH2, =NH, and =N- reactive sites
Summary of findings:
2,3-dimethyl-2-butene shows a unique lack of chemical reactivity on Si(100);
Coadsorption of ethylene and nitrobenzene provides a model surface with molecular-level feature control
Surface “basicity” can be predicted computationally and used as a measure of reactivity on model and practical reactions
Complex thermal desorption data can be analyzed by multiple curve resolution analysis as illustrated in a figure below
