Title : Multifunctional Nanocomposites for Clean Energy Generation and Environmental Remediation
Abstract:
With the ever increasing demand for energy and also due to increase in environment pollution, there has been lot of interests to develop novel materials for clean energy generation and also for cleaning environmental pollution. Hydrogen is being considered as a clean energy fuel and using a Photoelectrochemical method is a very promising way of generating H2 by photoelectrolysis of water. We have designed and synthesized several nanocomposite material by coupling semiconductor-semiconductor, semiconductor-polymer, semiconductor-ferromagnet, semiconductor ferroelectric and semiconductor-graphene nanostructures and explored its potentiality for enhancing the PEC H2 generation.

Organic dyes contaminated industrial waste water is highly toxic and posing serious problem to living organisms and whole eco systems. Semiconductors photocatalysts has engaged as an attractive technique to decompose the organic dyes, however the challenge is to develop visible light active, efficient and stable photocatalysts. We have developed visible light active, stable nanocomposites by combining semiconductor nanostructures of different band gaps and RGO, PANI or with appropriate ferroelectrics which exhibit much enhanced photocatalytic activity for the organic dyes degradation.
