The present invention relates to particles comprising copper oxide (CuO) and zinc oxide (ZnO); And a porous coating layer containing a metal oxyhydroxide formed on the surface of the particle; A method for producing the same; And its use. The catalyst of the present invention has an advantage of preventing the sintering of copper which is the active point of the catalyst, thereby improving the stability of the catalyst, maintaining the activity continuously, and reducing the catalyst at a relatively low temperature. |
