Project type

Exploratory Research

In order to model the chemical reactions catalyzed by supported vanadia, a model needs to be constructed. The defective anatase (101) surface will be modeled by a periodic slab. We have identified at…

103Rh and 13C NMR studies of Rh complexes used to Catalyze the Oxidative Carbonylation of Toluene to Toluic Acid
