catalytic modeling framework schematic (IMAGE) DOE/Brookhaven National Laboratory Caption Schematic of the theoretical framework: Starting with a computational model of the prepared catalyst, the scientists use density function theory calculations and kinetic modeling to map out phase changes under different reaction conditions. With this approach they can discover how reaction conditions affect the active phases of the catalyst and how they can be used to influence catalytic performance.
