In News- A team of researchers at the Indian Institute of Technology (IIT-BHU), has made significant achievements in developing nanomaterials based supercapacitors to achieve high energy density and power density of supercapacitors.

Key Points:

  •  IIT (BHU) has also developed a reduced graphene oxide (rGO) at a moderate temperature of 100°C with high capacitance performance.
  • Researchers have also developed a novel green approach for the synthesis of Iron-based nanocatalyst, which can be used for large scale production of Carbon Nanotubes.

 Surface-Enhanced Raman spectroscopy (SERS):

  • Surface-enhanced Raman scattering (SERS) is a technique which offers orders of magnitude increases in Raman intensity, overcoming the traditional drawback of Raman scattering – its inherent weakness.
  •  Researchers are working on developing novel nanostructures of carbon and metal dichalcogenides semiconductors for photodetection and Surface-Enhanced Raman spectroscopy (SERS).


  • The automobiles can run longer distances without charging as the high energy density of supercapacitors allows constant current to move for a longer duration without recharging.
  • Energy and optoelectronics devices will pave the way for the development of cost-effective and efficient devices, which can be used for energy storage application.
  •  Their findings make way for materials which can be used as advanced photodetectors and also be used as optical sensors for water pollution control.
  • The production process is a cost-effective one, making it suitable for commercial purposes.
