Production of hydrogen from natural gas remains to be an actual task. In a present study, a series of NiO-CuO-Al(OH)3 catalysts was prepared using a mechanochemical activation method under varied conditions. Among the considered parameters are centrifugal acceleration value (an), the motion mode of the milling balls, and their diameter. Although these parameters did not affect the phase composition of the obtained powders noticeably, they influenced the dispersion and distribution uniformity of the components and, thus, affected the catalytic activity in the catalytic chemical vapor deposition of methane. At an = 40 G, the prepared powders possess the maximum possible dispersion and distribution uniformity of metal oxides. In the case of the optimized preparation conditions, the achieved hydrogen productivity was as high as 215 Nm3/(kgcat×h). Carbon nanofibers, which are the solid-phase product of the process, possess a stacked and coaxial-conical structure and have a diameter of 10-120 nm.
