Progress in the preparation of coal pitch-based porous carbon and its application in supercapacitors
摘要
Abstract
The use of coal tar pitch(CTP)as a carbon precursor for the preparation of coal pitch-based porous car-bon(CPC)electrodes in supercapacitors represents an effective and sustainable approach to utilizing coal resources.This method not only enables the refined,high-value,and efficient utilization of coal but also contributes to the ad-vancement of energy storage technologies in the renewable energy sector.Recent studies have focused on various strat-egies for the synthesis and modification of CPC,including the regulation of pore size and structure,design of mor-phology,and optimization of surface chemical properties.These efforts aim to enhance the performance of CPC in su-percapacitor applications.However,there is a need for a deeper understanding of the intrinsic mechanisms behind these engineering strategies.Specifically,the relationship between synthesis methods and the composition,phase,reactivity of polycyclic aromatic hydrocarbons in CTP,as well as the degree of graphitization of CPC,requires further exploration.Recent research should be summarized to evaluate the electrochemical performance of CPC electrodes and compare their underlying mechanisms.Furthermore,while template-assisted and activation methods have been widely used to control the pore size of CPC,limitations persist,and future research should focus on employing a combina-tion of synergistic techniques for more precise separation of coal tar.Techniques such as supercritical extraction,air purification,and colloidal structure control should be prioritized.Additionally,more suitable oxidants and optimized oxidation conditions should be identified to improve the oxidation process.The fabrication of coal pitch-based carbon spheres and fibers faces challenges related to nanoscale tuning,necessitating the introduction of surface modifiers to reduce surface free energy or the adoption of more effective oxidation stabilization methods to preserve morphological integrity.Future research should also investigate the synergistic effects of different heteroatoms in CPC electrodes to enhance their performance.The ultimate goal of this research is to develop CPC products that strike a balance between cost-effectiveness and performance,ensuring their suitability for use in supercapacitors and other new energy devices.A variety of research strategies and the integration of multiple technical means under the premise of ensuring cost and operability to achieve the ultimate research goal could be adopted in the future.关键词
