Who we are
aLexis T. Bell
Dr. Bell’s interests are focused on experimental and theoretical studies of heterogeneous catalysis with an emphasis on defining the composition and structure of active sites and the mechanism and kinetics of reactions.
In JCAP, he conducts fundamental studies of the electrochemical oxidation of water and the reduction of CO2, experimental and theoretical investigations of catalyst structure-function relationships, and simulation of electrochemical cells used for the reduction of CO2 to fuels.
