Student thesis: Doctoral ThesisDoctor of Philosophy


The disposal of waste plastics has raised significant concerns about environmental pollution and the efficiency of raw material use. This paper reports the development of high-yield carbon nanotube catalysts for the thermochemical conversion of waste plastics from the perspective of industrial-scale production. Because the catalyst is not only related to the yield of carbon nanotubes, but also to the purity and uniformity of carbon nanotubes. This research focuses on the development of catalysts, so that higher yields, higher homogeneity, and simpler purification of the produced carbon nanotubes can be achieved, thereby promoting the potential commercial large-scale production of plastic carbon nanotubes.
