Synthesis, characterisation and evaluation of novel green solvents with properties tuned for CO₂ capture
The physical, chemical and transport properties of new green solvents are determined and their CO₂ absorption capacities are measured. Both thermodynamic and kinetics data are generated in order to elucidate the mechanism of reaction between CO₂ and these new solvents. Absorption/desorption cycles are carried out in order to investigate the reusability of these solvents.

Development of new solid sorbents for CO₂ capture
In this study, amine-functionalised solid adsorbents are synthesised and their performances in fixing CO₂ are evaluated. The study focuses on determination of adsorption isotherms as well as evaluation of breakthrough curves.

Development of new gas-liquid contactor technologies such as membrane contactors for CO₂ absorption process
Commercially available membrane modules such as hollow fibre type modules are used as contactors for the capture of CO₂ from gas streams. Conventional as well as novel solvents are used in this study. The performance of the membrane contactors is benchmarked to that of conventional packed bed absorbers.

Development and optimisation of CO₂ conversion processes
This part involves the application of the concept of process intensification to develop more efficient and sustainable routes for the transformation of the captured CO₂ to useful fuels and chemicals. Electrochemical processes are employed to convert CO₂ in the gas as well as in the liquid phase. These processes involve the development of new catalysts especially biocatalysts.
