Abstract
Low-rank coals are highly regarded as valuable precursors for carbon materials because of their ample reserves, high levels of polycyclic aromatic hydrocarbons, substantial carbon content and cost-effectiveness. Nevertheless, challenges in precisely manipulating the structure and characteristics of carbon materials derived from low-rank coals stem from the differences in ash content, microstructure, and interfaces across various low-rank coal sources. Recent research has provided strategies for governing the microstructure and surface attributes of carbon materials derived from low-rank coals. This review provides an overview of strategies for the preparation of adsorption active carbon, capacitive carbon, hard carbon, graphite and nano-carbon materials from low-rank coals. It also examines the influence of coal type and processing techniques on the microstructure, interface properties and functional group in them. The applications of coal-derived carbon materials in adsorption, supercapacitors, and alkali metal batteries are explored, and potential avenues for future research and its challenges are considered.
期刊介绍：
New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
