phase transfer catalyst lab 10 explanation

We propose to use advanced computational chemistry approaches implemented on massively parallel computers to develop a quantitative description of catalysts so as to develop new design criteria and to develop new understanding of the physical phenomena that occur at different spatial and temporal scales and that underlie catalytic behavior. The catalytic behavior is governed by their size and shape, interaction with the support, composition and atomic configuration for metal alloys and mixed metal oxides, the influence of solution as well as the presence of electric fields or applied potentials. Similarly, supported metal particles and metal oxides are complicated by their complex and ill-defined structure. For example, the specific atomic structural configuration and chemical makeup of the ligands that surround an active organometallic center in homogeneous catalysis and the pore size, local acidity, and specific atomic structure in zeolite control their activity and selectivity in ways that are similar to that found in enzymes. These processes are explicitly controlled by the intrinsic bonds that form between the reactants or intermediates and the active catalytic site as well as by the local nanoscale environment about the site. Abstract Catalysis is governed by a delicate balance between a myriad of competing bond making and breaking processes including adsorption, reaction, desorption, and surface diffusion that occur at active catalytic centers.
