Nanomaterials for Water Pollution Control—Developed by DST INSPIRE

Current Context: A team from INSPIRE, under the Department of Science & Technology (DST), has developed nanomaterials based supercapacitors to achieve high energy density and power density of supercapacitors.

• The supercapacitors will help to meet the energy demand due to the growth in the human population and technological advancement that poses a great challenge for human society. The high energy density of supercapacitors suggests that constant current can be withdrawn for longer duration without recharging. With this feature, the automobiles can run longer distances without charging. Supercapacitors can be an alternative for such purposes.
• The team aims to develop novel nanostructures of carbon and metal dichalcogenides (have the ability to achieve high energy density and power density of supercapacitors) semiconductors for photodetection and Surface-Enhanced Raman spectroscopy (SERS).
• This innovation has lead a way for the development of cost-effective and efficient devices, which can be used for energy storage applications.
• The novel nanostructures of carbon will make way for materials that can be used as advanced photodetectors and also be used as optical sensors for water pollution control.
