ABSTRACT

Diminishing fossil fuels and increase in the demands of energy worldwide, has led to the subsequent development of innovative technologies for sustainable energy supply. Some of the key technologies which can play a major rolein this context include; the conversion of biomassinto fuels and chemicals, andthe development of fuel cells for the efficient conversion of chemical energy into electrical energy. In most cases, underneath the development of these technologies lies the molecular level design and development of a catalyst material which can carry out the desired reactionwith high conversions and selectivities. Catalyst design at the molecular level is carried out by conducting experiments augmented with abinitio theoretical modeling and study ofthe reaction mechanism.

In order to elucidate the molecular level design of a catalyst material, three specific cases are discussed. In the first case, the ring opening and decarboxylation of a pyrone molecule derived from biomass was carried out in aqueous phase to produce valuable industrial chemicals. In the second case, mechanism of oxygen reduction reaction on a fabricated thin-film electrode of solid oxide fuel cell (SOFC) was studied. Detail understanding of the reaction mechanism leads to a better design of the catalyst. As the third case, a bimetallic catalyst was designed for the conversion of syngas to ethanol with enhanced activity and selectivity.
