Na related nanowhisker-containing biochar obtained from self-catalyzation and functionalization of papermaking black liquor lignin with superior heavy metal immobilization capability
{{output}}
In this study, papermaking black liquor lignin (ULG) was directly used to produce biochar through pyrolysis. It was found that ULG has a high ash content (15.38 %), primarily consisting of Na-related minerals. During pyrolysis, the ash can reduce the activatio... ...
