Deactivation of solid catalysts is an important issue in chemical industries and other catalytic applications. One of the causes of deactivation is the loss of active component due to corrosion or leaching by the reaction medium.
The team found that the loss of the active metal component is governed by the structure of the catalyst surface and the pressure (coverage) of carbon monoxide. They concluded that Pd leaching is likely under common catalytic conditions.
