    摘要： The invention provides a process for producing methanol. The process comprises contacting a gas phase with a solid catalyst, wherein the gas phase comprises (a) H 2 and (b) C0 2 , CO or a mixture of C0 2 and CO, and the catalyst comprises heterometallic particles comprising palladium and zinc. The invention also provides a catalyst which comprises heterometallic particles of palladium and zinc and a support material comprising zinc oxide. Also provided is a process for producing such a catalyst, the process comprising reducing a composition comprising palladium and zinc oxide. A catalyst obtainable by this process is also provided. The invention also relates to uses of the described catalysts for the hydrogenation of C0 2 , CO, or a mixture of C0 2 and CO, to produce methanol, and, more particularly, for the hydrogenation of C0 2 to produce methanol. The invention also provides a composition which comprises palladium, zinc oxide and a compound suitable for promoting the reduction by hydrogen gas of zinc oxide to zinc metal.
