Our Research

Our research majorly involve chemical synthesis of novel nanostructured materials and their applications in catalysis, photocatalysis, fuel cells, and supercapacitors.

Morphology Controlled Synthesis of Nanocrystals

The properties of nanomaterials are known to vary with the shape and size, which thereby have strong implications on their performances in potential applications. One of the strong reasons for this is the exposed facets of crystal which changes with its shape. Below figure shows the photocatalytic performance of different shaped TiO2 nanocrystals.


The photocatalytic activity of TiO2 NCs with different shapes for the degradation of MO and MB. The rate constants values are compared with the specific surface area as dye degradation follows the adsorption onto the catalyst surface prior to degradation in presence of light.

Composite Catalyst for Improved Oxygen Reduction Reaction (ORR)

We fabricate different composites using nanostructured oxide as catalyst material and graphene/conducting polymer as support to be used as electrode in fuel cells.


MnO2-NTs/graphene composite as promising cathode catalyst to replace Pt for ORR

Catalyst for Improved Hydrogen and Oxygen Evolution Reaction (HER and OER)

The suitable oxide nanomaterials are normally tested for oxygen and hydrogen evolution reaction.
