The combustion of fossil fuels releases close to 40 billion tonnes of CO2 to the atmosphere every year, leading to adverse climatic change and ocean acidification. Electrocatalytic conversion provides a potential solution to this problem, where the greenhouse gas is converted into valuable products, such as methanol, formic acid, methane and ethanol. Direct conversion from the atmosphere, in particular, is a highly promising approach for tackling emissions from distributed sources and reduce the concentration from the atmosphere.
However, due to the low concentration of CO2 in the atmosphere (~ 400 ppm), direct conversion without pre-concentrating the feed gas is challenging. Currently leading technologies rely on solid adsorption or solvent absorption to pre-concentrate the gas, which requires high energy input (30 to 400 kJ/TCO2) during the regeneration to recover the captured CO2, thus making the process unscalable.
This project seeks to develop novel asymmetric CMS membranes with capacity to efficiently capture CO2 from the atmosphere, while also providing hosting sites for sub-nanometre scale electrocatalysts, for CO2 conversion. The student’s task will include; (i) investigating the link between the physicochemical properties of polymer precursors and the pore size distribution, (ii) tuning the pore structures such that one side of the CMS membrane is optimized for CO2 capture, while the other side will have relatively larger pores to allow for modification with the electrocatalytic nano-catalysts, (iii) investigating the correlation between pore size distribution and the CO2 capture efficiency from the atmosphere.
Applications will remain open until a candidate has been appointed.
