Abstract
It is shown that a pure Cu catalyst is inactive in methanol synthesis. Activity can be invoked by small amounts of (alkali) promoters. Contaminations present in the current commercial supports are leached out during impregnation and promote Cu sufficiently to produce methanol. Contaminations-promoters slow down the reduction of Cu precursors.
