The dispersion of heterogeneous catalyst is directly related to the performance. In this work, highly dispersed Cu/graphene catalyst was successfully prepared by adopting a “template genetic inheritance” (TGI). The metal‐organic frameworks (MOFs) were introduced between the graphene sheets. Due to the spatial structure of MOFs, the Cu atoms arranged in the expected direction after removing the MOFs skeleton, which lead to a highly orderly dispersion of the Cu particles with uniform sized. Meanwhile, graphene provided a large specific surface area and a carbon source for in‐situ reduction of CuO. Furthermore, the CO 2 hydrogenation to methanol performance was analyzed and more than 22 % conversion of CO 2 and 84 % selectivity of methanol was achieved. This work provides a simple and novel strategy for the preparation of highly dispersed metal particle supported catalysts, which may be used in catalysis and other fields.
