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 Infiniti Q45 produces into harmless molecules of carbon dioxide, oxygen, and some water. This process revolutionized automakers' ability to improve air quality, which is why every vehicle made today has a catalytic converter.
