In order to support a growing global population and advance quality of life in a way that is sustainable for the planet, rapid development of green chemical processes as well as聽clean and renewable energy sources as well as energy efficient are essential.聽 These areas are linked by energy conversion (e.g., light to electrical, thermal to electrical, electrical to chemical) and molecular transformations (the creation of bonds and chemical structures) where the control of mechanisms, catalysis and the flow of energy is critical for designing efficient and clean transformations capable of producing critical materials ranging from fuels to pharmaceuticals.

Energy, Catalysis, Chemical Transformations

Energy and chemical transformations are linked by catalysis, which controls efficiency both in terms of energy consumption as well as the nature of the products (including unwanted by-products - waste).聽 A uniting primary theme among the CTRI team is the development of catalysts based on Earth-abundant elements (including main group elements and transition metals) that are engineered with ligands that impart unprecedented catalytic activity and selectivity. By focusing on Earth-abundant elements as well as developing robust and easily synthesised systems, the team ensures that catalysts and the sought-after chemical transformations they are used for are sustainable, inexpensive, and greener.

Organic-based Energy Storage and Conversion

Replacement of established inorganic-based energy storage and conversion systems such as lithium-ion batteries and silicon-based solar cells with inexpensive and more easily produced organic-based systems has the potential to transform the energy landscape. Organic chemistry offers the unique ability to engineer the electronic structure of molecules to control the flow of charge in a wide range of electronic devices that have already reached the consumer market such as organic light emitting Diodes (OLEDs) and organic thin film Transistors (OTFT). It is only a matter of time before organic materials become a central component of energy conversion and storage systems.
