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