• Metal Oxide heterojunction

In semiconductor photocatalysis heterojunction and its types have a major role in controlling the charge separation and transport. Taking advantage of this, our group is developing/developed highly effective multiphasic homo-heterojunction composites for efficient solar photocatalytic detoxification and disinfection applications.

• Plasmonic Metal Oxide heterojunction

Surface plasmon assisted semiconductor photocatalysis is one of the most emerging techniques to improve the photon absorption, charge carrier separation and charge transport in a semiconductor. Looking at the improved optical properties of the metal-semiconductor junction, our group is developing/developed highly effective multiphasic plasmonic homo/heterojunction composites for efficient solar photocatalytic detoxification and disinfection applications.

•  Metal Oxide Nanostructures

Surface area and morphology of the semiconductor photocatalyst have a major role in controlling the photon absorption and charge transport. Taking advantage of this, our group is developing/developed highly effective morphologically tuned multiphasic homo/heterojunction composites for efficient solar photocatalytic detoxification and disinfection applications.

• Z-Scheme Photocatalysts

In recent years, Direct Z-scheme based photocatalysts has emerged as the most promising one as it maximizes the redox potential and enables effective spatial charge separation. The widely reported g-C3N4-based direct Z-scheme systems includes g-C3N4-wide band gap SCs, g-C3N4-narrow band gap SCs and g-C3N4-based ternary composite. Keeping this in mind, our group tries to identify the challenges and future prospects of g-C3N4-based direct Z-scheme systems for energy and environmental applications.

• Photocatalytic Reaction Parameters

Along with material engineering, the photocatalytic reaction environment also plays a vital role in the photocatalysis process. Keeping this in mind our group is also working on the optimization of photocatalytic reaction parameters such as catalyst loading, reaction temperature, light intensity, dispersion of photocatalyst, dye concentration etc.

• Photocatalytic Reactor

Photocatalysis is one of the easy and sustainable technique for water and air treatment. Photocatalysis process in slurry mode are efficient in lab scale but its commercial applicability is limited due to lack of effective separation method for the catalyst. The development efficient photocatalyst alone cannot help the commercialization of the photocatalysis process. It requires an appropriate and efficient photocatalytic reactor with fixed mode catalyst loading and easy replacebility. In this aspect our group is developing fixed mode continuous photocatalytic reactor.
