The Front Cover shows that NO x removal from exhaust gases is very fast with catalysts containing vanadia supported on ceria while iron in the ceria support “throws a wrench in the works”. In their Full Paper, S. Keller et al. show that iron boosts the catalytic performance of bare Ce 1‐x Fe x O 2‐δ solid solutions while, unexpectedly, iron is detrimental when vanadia is supported on their surface. In situ XANES, operando DRIFTS and EPR studies showed that Fe 3+ is partly reduced to inactive Fe 2+ , favours clustering of VO y sites and damages active V‐O‐Ce junctions.
