A summary of the catalytic control of carbon monoxide (CO), volatile hydrocarbons (either HCs or VOCs), oxides of nitrogen (NOx) and total particulate matter (TPM) emissions from mobile and stationary sources is presented. The chapter begins with a brief introduction to the fundamental principles of heterogeneous catalysis. The three-way catalytic converter (TWC) and the electronic control system for controlling CO, HC and NOx from gasoline-fueled engines is described. Controlling emissions from diesel engines with the introduction of the diesel soot filter for soot or TPM control is discussed. Two technologies for reduction of NOx from diesel trucks (selective catalytic reduction) and passenger cars (lean NOx traps) are described. Modifications of these technologies in use for emission control from stationary sources are described. The chapter ends with a look to sustainable technologies that may generate power without pollutants and with lower greenhouse gas emissions.
