Abstract:	Catalytic hydrogenation of CO₂ into methanol has been investigated over Raney Cu-based catalysts. The Raney catalysts leached in NaOH/ZnO solutions showed high activities and selectivities for methanol synthesis. The deposition of Zn on the surface of Cu particles increased the surface area and the specific activity of Raney Cu–M. Raney Cu–Zr developed was significantly more active than a commercial catalyst.

Keywords:	CO₂ hydrogenation into methanol Raney Cu–Zr catalyst Methanol activity Leaching in NaOH/zincate solutions
