Investigating the influence of surface impurities in metal oxides for chemical looping

Perovskites are promising oxygen carrier materials, able to release a significant proportion of their lattice oxygen to the environment under relevant conditions. Provided the material is phase-pure, this release is reversible. However, the presence of surface impurities may impact the release and uptake rates of oxygen of the material. This thesis aims to understand the impact of surface impurities on these rates, by investigating their surface concentration and nature using advanced material characterisation techniques, and evaluating the oxygen release and uptake rates using thermogravimetry.
