Research progress on the preparation and application of lignin-based carbon catalysts

Lignin is an ideal precursor of carbon materials because of its three-dimensional network aromatic ring structure, abundant source, high carbon content, rich and controllable functional groups. Lignin-based carbon materials with special functions could be fabricated through chemical modification and microstructure regulation, which were widely used in the fields of energy catalytic conversion, electrochemical energy storage and environmental remediation. In this review, the latest research progress of lignin-based carbon material catalysts was presented, and the preparation methods of lignin-based carbon material catalysts were summarized. What's more, it focused on the fundamental research progress of lignin-based carbon material catalysts in the thermal catalytic reaction such as oxidation reaction, hydrogenolysis reaction, esterification reaction, hydrolysis reaction, dehydration reaction and Fischer- Tropsch synthesis, electrocatalysis such as hydrogen evolution reaction in water splitting and oxygen reduction reaction in Zn-air battery, as well as photocatalysis of organic pollutants degradation. However, it was still a challenging task to build the lignin-based carbon material catalyst with high activity, high stability, low cost and large-scale production. In the future research, it was necessary to strengthen the research on the basic chemical structure and microstructure regulation of lignin, the interaction between active components and lignin carbon material support, and the enhancing mechanism of lignin-based carbon material catalyst in the catalytic reaction, so as to make use of its advantages of low cost, three-dimensional structure and adjustable microstructure characteristics, and to expand the fields of high-value utilization of lignin biomass resources.
