Abstract:
The global energy demand is rapidly escalating with increasing levels of greenhouse
gases and pollutants. Hence, there is a well-established need for transition towards a green
and sustainable global economy. This facilitates the development of new energy technologies
using renewable energy sources that can meet the end user requirement without posing a
threat to our environment. The real challenge to achieve this transition lies with respect to
reduction in cost of the available renewable energy sources. Electrochemical energy systems
play a significant role in energy sustainability due to their high efficiencies and quite
negligible chemical and noise pollution. The core of the electrochemical energy conversion
and storage technology involves the development and designing of highly efficient and
durable materials that can effectively catalyze various electrochemical reactions needed to
facilitate the transition towards a greener economy. This thesis is aimed to address the
environmental issues using the electrochemical approach by designing and development of
various catalytic materials that will favor energy conversion, storage and fuel production.
