Electrification of catalytic methane decomposition to hydrogen and nanostructured carbonaceous materials

The catalytic decomposition of methane to produce hydrogen and carbon is an economically and environmentally attractive approach to creating a CO/CO 2 -free cycle for hydrogen production. In order to achieve this, it is crucial to use electricity from renewable or alternative energy sources that operate without CO/CO 2 emissions. Currently, however, most developments have not progressed beyond the laboratory level. This paper summarizes the current status and perspectives of the main methods of catalytic methane decomposition electrification. This review provides an outlook on producing nanostructured carbonaceous products, such as carbon nanotubes, nanofibers, graphene, and graphite. By systematically summarizing literature on this topic, we provide a comprehensive, simplified overview of the field, emphasizing catalyst and reactor design, as well as possible routes to the electrification of catalytic methane decomposition, including plasma, microwave, and induction heating.
