Computational Chemistry

Main content

Our group uses state-of-the-art computational methods to unravel the structure and reactivity of single-site catalysts such as grafted metal complexes, oxides and zeolites.

 
Cooperativity between Al Sites Promotes Hydrogen Transfer and Carbon–Carbon Bond Formation upon Dimethyl Ether Activation on Alumina. (ACS Cent. Sci., 2015, 1 (6), pp 313–319.)
Adjacent Lewis acid sites on alumina play in concert to activate dimethyl ether via H-transfer yielding CH4 and surface formate or olefins and H2O. (ACS Cent. Sci., 2015, 1 (6), pp 313–319.)
