“…Additionally, with a three‐dimensional network structure formed by phenylpropane units, lignin is rich in phenolic hydroxyl groups, alcoholic hydroxyl groups and part of carboxyl groups, and its carbon content is as high as 60% 40,41 . Furthermore, lignin‐derived carbon has recently been reported as the catalyst support in the applications of electrocatalysis, 42,43 photocatalysis degradation, 44,45 Fischer‐Tropsch synthesis, 46 and other fields 47,48 . However, most lignin‐derived carbon catalysts are prepared using the direct carbonization of lignin followed by the impregnation of metal active ingredients, which are easily dissoluble and difficult to effectively inhibit their agglomeration, resulting in the inferior activity, and durability 49…”
