 The study investigated the use of a new method called carbon erosion, CE, to create nickel-copper catalysts for the production of carbon nanofiber, CNF-based composites. This method involves the use of a planetary mill to mix two different types of metal powder together, followed by heating and reduction in a hydrogen atmosphere. The resulting catalysts are then exposed to a reaction mixture containing carbon dioxide, hydrogen, and argon gas. The catalysts are then used to produce CNF-based composites, which can be characterized using various techniques including scanning and transmission electron microscopy.
