Unraveling the Catalytic Graphitization Mechanism of Ni-P Electroless Plated Cokes via In Situ Analytical Approaches.

ABSTRACT: We elucidate the catalytic graphitization mechanism using in situ analytical approaches. Catalytic graphitization is achieved through a Ni-P electroless plating process at a relatively low temperature of 1600 °C, which allows for a high crystallinity of coke. We also employ an ultrasonic treatment during the Ni-P electroless plating stage to effectively form metal layers on the surface. The impact of the ultrasonic treatment on the Ni-P electroless plating is confirmed by field emission scanning electron microscopy images of the cross-section and an elemental composition analysis using energy dispersive X-ray spectroscopy mapping. Structural analysis of the graphitized cokes via X-ray diffraction (XRD) and Raman spectroscopy shows that Ni-P electroless plating significantly accelerates the
