Ph.D. Thesis Adjudication

A number of Ph.D. theses submitted to various universities/Institutes were adjudicated.

Research group “Nanocatalysis and Solar Fuels Research Laboratory” on the following research topics:

 

[1] Nanocomposite Photocatalysts for Green Hydrogen Production

Photocatalysis alike “photosynthesis” process, where visible light absorbed by a semiconductor triggered a series of reduction and oxidation reactions with in-situ generated electron/hole pairs, that worked very well at ambient temperature and pressure. This topic involved three inter-disciplinary subjects viz., semiconductor physics, surface science and heterogeneous catalysis.

 

Photocatalysis has been extensively studied for energy and environmental applications. Besides several benefits, a large-scale demonstration of photocatalytic hydrogen production requires the development of nano-sized catalyst material that involves rapid separation of electron/hole pairs in-turn effectively utilized the same to trigger a series of chemical reactions.

 

Research publications witnessed “efficient separation and utilization of photogenerated charge carries” through cation/anion doping, formation of homojunction or different types of heterojunctions, nanostructures and a variety of micro-, meso- and macro- porous supported photocatalyst systems.

 

The major highlight of the research work is the use of earth-abundant materials, a simple concept and scalable experimental methods in the preparation of photocatalysts.

 

This research group has significant contribution to the design and development of more than 25 nanocomposite photocatalysts for the high rate of hydrogen production in the following approaches.
• Successful in the preparation of binary, ternary, and quaternary nanocomposite photocatalysts.
• Chemical synthesis of Transition metal oxides, Metal Chalcogenides, Carbon nanostructures and Carbon nitrides based on Zero, One and Two -dimensional nanostructures.
• Core-shell morphology as photocatalyst and co-catalyst.
• Heterojunction photocatalysts based on Schottky, Type I, Type II, Z-scheme and S-scheme. • Gram scale synthesis of highly efficient photocatalysts.
• Utilization of industrial by-product glycerol, H2S-containing wastewater and organic dyes for conversion of waste into clean H2 fuel.
• Utilization of seawater and effective utilization of natural sunlight for photocatalytic H2 generation.
• Demonstrated quantum efficiency using a solar simulator with bandpass filters.
• Batch and demonstrative photoreactors for H2 production.
