Abstract

See full text

The present invention relates to catalytically active material, comprising grains of non-graphitizing carbon with iron nanoparticles dispersed therein, wherein dp, the average diameter of iron nanoparticles in the non-graphitizing carbon grains, is in the range of 1 nm to 20 nm, D, the average distance between iron nanoparticles in the non-graphitizing carbon grains, is in the range of 2 nm to 150 nm, and ω, the combined total mass fraction of metal in the non-graphitizing carbon grains, is in the range of 30 wt % to 70 wt % of the total mass of the non-graphitizing carbon grains, and wherein dp, D and ω conform to the following relation: 4.5 dp/ω>D≥0.25 dp/ω. The present invention, further, relates to a process for the manufacture of material according to the invention, as well as its use as a catalyst.
