| Abstract Scope |
The Fe/molten salt electrolysis dual-driven graphitization process provides a fast and green solution for the efficient conversion of waste biomass into graphitized carbon. To investigate the kinetics of the Fe-promoted graphitization process, a series of characterizations were conducted using X-ray diffraction and Raman spectroscopy. Based on this, the focus was on kinetic analysis, exploring and establishing kinetic equations for both catalyst-present and catalyst-absent systems, and systematically studying the evolution of graphitization degree with respect to electrolysis temperature and time. The results indicated that the Fe significantly reduced the activation energy of the graphitization reaction and increased the graphitization transformation rate constant, thereby accelerating the removal of impurity atoms and the rearrangement of the carbon skeleton. This study not only quantifies the catalytic mechanism of Fe in electrolytic graphitization at the kinetic level but also provides theoretical basis for the large-scale preparation of high-value-added graphitized carbon from low-quality carbon-containing solid waste. |
