Structure of Coal-Derived Metal-Supported Few-Layer Graphene Composite Materials Synthesized Using a Microwave-Assisted Catalytic Graphitization Process

At a temperature of 1300 °C, we quickly converted earth-abundant and low-cost bituminous coal to FLG over Fe catalysts. At 1300 °C using a S10% Fe catalyst for 20 min, the highest degree of graphitization and a well-developed pore structure were made. The metal-supported FLG was manufactured using microwave-assisted catalytic graphitization, according to a three-to-layered graphene nanosheets, according to a high-resolution transmission electron microscopy report. In addition, the 2D band at 2700 cm-1 in the Raman spectrum of the fabricated metal-supported FLG samples was found, which indicated the presence of a few-layer graphene structure.

The catalytic effect of iron on the graphitization of diamonds

Fe-15 wt. % diamonds were processed by means of traditional powder metallurgy with the properties of cold pressing at 350 MPa and sintering at 1100°C/360 min. Using thermal analysis, the oxidative behavior of diamonds was investigated. Using infrared spectroscopy, the absorption bands of the graphite and diamond structures' C-C bonds were investigated.
