Structure of Vehicle Exhaust Emission Control Catalyst and Role of Rhodium

Rhodium contributes towards eco-driving by eliminating nitrogen oxide, the cause of acid rain.

By eliminating the harmful pollutants in vehicle exhaust gas, three-way catalysts prevent the release of those pollutants into the atmosphere. Using rhodium to reduce acid rain-causing nitrogen oxide back to nitrogen, and platinum and palladium to catalytically combust hydrocarbon into harmless water, and carbon monoxide into carbon dioxide, catalytic converters exhaust clean gasses.
