Co-Fe bimetallic catalyst can be prepared by a facile reactive ball-milling method for highly active and selective hydrogenation of CO 2 to the C 2 = –C 4 = and C 5 + species. Reactive ball milling can generate CoFe phase for efficient CO 2 activation, and promote in-situ structural evolution to Co 2 C and Fe 5 C 2 for C–C coupling reaction.

For reactive milling, the vial was put in a high energy ball mill equipped with a rotary pump and a gas flow system [70,71]. The XRD patterns of the initial elemental hcp-Ti powder samples milled under 10 bar of nitrogen gas for …
Ball Milling
Reactive ball-milling (RBM) technique has been considered as a powerful tool for fabrication of metallic nitrides and hydrides via room temperature ball milling. The flowchart shows the mechanism of gas-solid reaction through RBM that was proposed by El-Eskandarany.
High-temperature high-pressure reactive ball milling …
High-temperature, high-pressure reactive planetary ball milling is applied for the synthesis of Mg 2 NiH 4. Elevated temperature promotes the formation of MgH 2 and Mg 2 NiH 4 mixture. Lack of strain hardening at elevated temperature prevents refinement of nickel particles and causes agglomeration.
