Controlling air pollution

Catalyic Converter

2NO + 2CO -----> N2 + 2CO2

  • As CO and NO gas molecules diffuse over the catalyic surface. Some molecules are absorbed onto the metal surface.


  •  This weakens the bonds and lowers activation energy


  • Then after the reaction, the CO2 and N2 products are desorbed from the surface and diffuse away from the catalyic surface.

Solutions to the greenhouse effect

Carbon Capture and Storage

Methods of CCS include:

  • Storage in geological formation such as underground porus rocks and old gas and oil fields
  • Reaction with metal oxides to form carbonates. Eg -

          CaO + CO2 ------> MgCO2

Problems - Very slow reaction
