摘要： The invention relates to a supported catalyst comprising a molded support and a layer that is made of a metal oxide of a main group metal, an early transition metal, or a lanthanoid, is arranged on the molded support, and is composed of individual particles. An oxide composition, the surface density of which corresponds at least to a monolayer and which contains molybdenum and/or vanadium and/or iron, is provided on the layer or on the individual particles. The invention further relates to the use of said catalyst for reacting methanol into formaldehyde.
