A method for catalytic vapor phase oxidation of methanol to formaldehyde may include: passing a feed stream comprising methanol and oxygen through a layered catalyst bed having a first layer comprising a first silver catalyst particles and a second layer comprising a second silver catalyst particles that are different than the first silver catalyst particles, wherein the feed stream passes through the first layer before the second layer, wherein the first silver catalyst particles has a greater reaction activity for converting methanol and oxygen to formaldehyde; and reacting the methanol and the oxygen in the presence of the catalysts to produce a product stream comprising formaldehyde.
