81% of all rhodium (Rh) is used in automobile catalytic converters. Consequently, researchers have dedicated a lot of effort into understanding the behavior of nonmetal oxides on a Rh surface. Using a computer simulation program, we have studied the absorption and oxidation of carbon monoxide (CO) on a terraced Rh surface (lattice) with a width of three and a height of 10000 using a mechanism that describes the behavior at low temperatures. Varying the reaction activation energies (rate constants), and the mobility of the CO, led to changes in the surface coverages of oxygen and CO. Specifically, increasing the activation …
