The unique catalytic properties of ceria and ceria-based materials are primarily determined by the easy switching between Ce3+ and Ce4+ oxidation states on the catalyst surface. This redox process is also important for other applications of ceria-based materials, such as their biomedical use. Therefore, in situ determination of the oxidation state of cerium cations located on different ceria planes

We are sorry that we have found a minor error in our published paper entitiled “Identifying a superior Ptδ+ species for the hydrogen-borrowing amination of alcohol at low temperature” (J. Catal. 432 (2024) 115407). Although it is not critical data and does not affect the corresponding conclusion, we still hope a smooth corrigendum to ensure its rigor.

Reliable assessment of electrocatalytic performance of novel materials to determine the oxygen reduction (ORR) activity plays a pivotal role in systematic-driven design of tailored composites. Unfortunately rotating disc electrode technique, typically employed for this purpose, is incapable to accurately predict the behaviour of promising candidates in membrane electrode assemblies (MEAs) which are
