Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that turn the carbon monoxide and hydrocarbons that your GMC R2500 produces into harmless molecules of carbon dioxide, oxygen, and some water. Thanks to this chemical reaction, automakers could now curb their contribution to air pollution, which is why every vehicle made today has a catalytic converter.
