| Abstract: |
The advancement of CO2 catalysis has progressed significantly in the last two decades owing in part to the increased awareness of climate change. CO2 capture and utilisation has become a major area of research for reducing atmospheric CO2 levels. The initial part of this thesis approaches the development of CO2 electrolysers from a design perspective whereby the cell was optimised for current density through modelling and experimental techniques. Cell parameters such as electrode separation, electrolyte concentration, flow rate and buffering effect, and electrolyte circulation system configuration were examined alongside the effect of increased cathode electrochemical surface area. The results showed that proton transport limitation due to the Nafion membrane was a limiting factor but only at high applied voltages. Next the effect of additive-modified copper foams was explored to optimise the faradaic efficiency for C2 products. With the inclusion of a gas diffusion electrode a considerable faradaic efficiency for ethanol was observed, whilst the lysine-modified copper foams showed a hydrogen quenching effect. |
