Abstract:

Lignin is a kind of natural polymer with three-dimensional network structure, large amount of aromatic groups and high carbon content. It has great potential in the field of preparation of porous carbon materials. Porous carbon materials have a great application prospect in the field of catalyst and the energy storage. Industrial lignin, as a byproduct from the pulp and paper and biological refining industry, is used to prepare porous carbon and used in energy storage, adsorption, catalyst carrier and other field, which can realize the high-valued recycling utilization of industrial lignin. This paper summarized the current lignin commonly used preparation methods of porous carbon materials and micro channel structure adjustment methods, and summarized the main characteristics of the various preparation methods, as well as the key factors affecting on the structure and performance of lignin-derived porous carbon materials. It focused on the research on pore control of lignin-derived porous carbon materials in recent years and summarized the pore regulation methods. Taking supercapacitors, adsorbents and catalyst carriers as representatives, the application status of lignin porous carbon materials in the field of catalysis and energy storage materials was reviewed, and the microstructure characteristics of lignin-derived porous carbon materials were discussed. The opportunities and challenges of lignin in the preparation and application of porous carbon were summarized and prospected.

Key words: lignin, porous carbon, channel regulation, energy storage material, adsorbent, catalyst support
