Plasmon enhanced photocatalysis for sustainable energy:

Plasmonic nanostructures can concentrate incident light as much as 1000 times in the near-field due to localized surface plasmon resonance. The strong electromagnetic field at the surface of plasmonic nanoparticles such as gold and silver can be utilized to manipulate the energy and electron absorption of vicinal photocatalyst or adsorbed reactant molecules. The design of novel catalysts using plasmonic nanostructures, which can efficiently exploit photon-induced charge and heat to drive energetically demanding chemical reactions at the relatively milder condition, is of both economic and environmental interests. Our research objective is to understand the detailed mechanism of interfacial energy and electron transfer among plasmonic nanomaterials and photocatalyst. We aim to utilize the knowledge gained from our fundamental study to design suitable photocatalytic systems for important reactions such as CO2 reduction.

PDMS sponge with nanocatalysts for waste water treatment:

PDMS sponges are suitable substrate for selective absorption of oils and organic solvents from water and can be elastically deformed into any shape, and can be compressed repeatedly in air or liquids without collapsing enabling excellent recyclability. In our lab we work on enhancing those sponges by incorporating nanocatalysts making them suitable for photocatalytic and antibacterial activities, thus promoting potential in environmental applications.

Optically active 2-D materials:

Two-dimensional layered nanomaterials such as molybdenum disulphide nanomaterials are optically active with potential applications in photocatalysis and photo-thermal therapy. We aim to understand the effect of their morphology such as defect and layer thickness on their bandgap and how will that affect their photon induced properties
