1. Multicomponent Catalytic Reactions : Theoretical and Experimental Studies
Abstract : In this thesis, Density Functional Theory (DFT) methods have been applied to study the mechanisms of three different multicomponent organic reactions. Also, a new synthetic procedure for the preparation of quinolinium salts is presented, and its mechanism also studied by DFT calculations. READ MORE

2. New Catalytic Systems for Light-driven Hydrogen Evolution
Abstract : Solar-driven reduction of water to produce hydrogen is one of the most promising ways to develop sustainable cleanenergy for the future. The challenge in photocatalytic hydrogen evolution research is to design inexpensive catalystsand construct efficient hydrogen production systems. READ MORE

3. Catalytic Asymmetric Ketone and Alkene Reductions Using Transition Metal Complexes
Abstract : This thesis contains seven papers dealing with iridium and ruthenium based catalytic asymmetric reductions, either of ketones into chiral alcohols, or olefins into chiral alkanes. The first part of the thesis describes how we have designed and evaluated new bicyclic ligands containing either N,S or N,N chelating atoms. READ MORE

4. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia
Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE

5. Water Splitting Mechanism on 2D Catalytic Materials : DFT based Theoretical Investigations
Abstract : In this thesis, we have envisaged systematic investigation to predict the water splitting mechanism on ultra-thin two-dimensional (2D) materials using cutting edge computation. Three different families of materials are considered as the case studies - i.MX2 (where M= W and Pt) based transition metal dichalcogenides, ii. READ MORE
