An MO for Mo: β‐MoO 3 /α‐Fe 2 O 3 catalysts synthesized by chemical vapor deposition exhibit a uniform shell–core structure. The structure of the metastable β‐MoO 3 film is retained even after calcination in air at 873 K, owing to strong MoOFe links at the interface. The shell–core β‐MoO 3 /α‐Fe 2 O 3 catalysts are much more active than, and comparably selective to, the reference α‐MoO 3 catalyst in the selective oxidation of methanol to formaldehyde.
