Area of Interest

Research Interests/Focus:

Synthesis of nanomaterials/structures or select/modify existing 2D materials to nanomaterials for electrochemical (EC) sensing, photocatalysis, and energy storage- supercapacitors and electrodes for battery applications.

EC sensors are attractive because of their remarkable detectability, fast response experimental simplicity, portability, and low cost. Our focus is on the detection and quantification of biomolecules, biomarkers for disease diagnosis, and toxic heavy metal ions (HMIs)/chemicals that pollute water. 

Lithium-ion batteries (LIBs) have the highest energy density among all the secondary battery systems. Nevertheless, current LIB technology is not sufficient to meet the requirements of the future, which demands and requires high performance/large-scale energy storage, and hence, there is a demand for better electrode materials with higher capacity.

Photocatalysis is a green and sustainable method that makes use of semiconductor materials to photodegrade pollutants in water using sunlight. Our interest has been in Titanium dioxide-based materials and modifying TiO₂ for better performance.

Material science has a vital role to play in the performance of these methods. In our work, we use chemistry and the advantage of nanomaterials to enhance the efficiency of the methods.
