Context: Researchers at IIT Mandi have developed a novel carbon-based catalyst to make water electrolysis more efficient.

  • Water electrolysis is the process of choice to produce ‘green hydrogen ‘thus making it more significant.

 

About water electrolysis:

  • In water electrolysis, water molecules are split into hydrogen and oxygen using electricity inside a device called an electrolyser. However, this process consumes a lot of electrical energy.

 

New finding:

  • A new study has reported a porous carbon material containing nitrogen that functions both as a catalyst and as the anode in electrolyser units – and could substitute the metal-based catalysts.
  • The researchers produced this material, called ‘laser carbon’, by exposing a sheet of a polymer called polyimide to a laser beam, which carbonised the exposed bits, leaving the remainder rich in nitrogen.

 

Advantages of the new catalyst:

  • Laser carbon is “highly power efficient”, cheaper to produce, has a simpler synthesis technique, and “can be batch-manufactured with a laser”.
