Supported palladium catalysts in environmental catalytic technologies for gaseous emissions

Palladium is the active component in several catalytic formulations for env ironmental technologies, due to its superior performances in the conversion of some hydrocarbons (for example, methane) and halocarbons, and the therm al stability and low volatility of Pd species. The proper-ties and reactivi ty of Pd-based catalysts in the conversion of methane catalytic combustion for gas turbine applications, reduction of greenhouse gas (methane, N2O) em issions, hydrodehalogenation and oxidative destruction of halocarbons and t heir applications in the elimination of other pollutants from gaseous emiss ions are reviewed, with emphasis on the structure-activity relationships, r eaction mechanism and sensitivity to poisoning.
