Key examples are cement and steel manufacture. These are essential to the UK economy and have global impact. Here we seek to utilise produced CO2 to provide valuable, carbon neutral products. This not only addresses climate change, but also adds commercial value.
Here, we seek to develop materials for CO2 electrolysis, basing this upon prior successes utilising Mn doped perovskites and exsolution chemistry. Key parameters are low electrochemical losses and resistance to coking in higher carbon containing atmospheres. This will entail materials and electrochemical studies, synthesising and characterising new target compositions, fabricating cells and evaluating electrochemical properties in relation to produced gases.

We will focus upon co-electrolysis of CO2 and steam seeking to develop efficient systems to produce synthesis gas without risk of coking. Three tasks will be pursued:
• La0.4Ca0.4 TiO3 and La0.43Ca0.37M? Ti1-?O3-γ (M = Ni0.05, Ni0.10, Ni0.05Mn0.05) powders were prepared by the solid-state reaction.
• XRD, SEM and TEM were utilized to characterize the exsolved nanoparticles.
• TGA was used to investigate the influence of different B-site doping on the number of oxygen vacancies formed.
