Engineers find neat way to turn waste carbon dioxide into useful material

  • An extremely hot flame is used to create nanoparticles of zinc oxide.
  • Using electricity, those nanoparticles can be turned into ‘syngas’ (hydrogen + carbon monoxide), a component for making industrial products.
  • Syngas is kind of like Lego - you can easily rearrange hydrogen and carbon monoxide to make synthetic diesel, methanol, alcohol or plastics.
  • All it would take is a simple electrolyser with zinc oxide, mounted in industrial plants, which would suck in the CO2 and turn it into syngas.
  • Other techniques of creating syngas require burning fossil fuels, or expensive materials like palladium - this technique is much cheaper and more scalable.
