A kind of high mesoporosity lignin hierarchical porous carbon material and its preparation method and application |
| abstract |
The invention discloses a lignin hierarchical porous carbon material with high mesoporosity and a preparation method and application thereof. Firstly, the lignin and hydroxycarbonate composites were prepared based on the hydrothermal reaction of the three-dimensional network structure of lignin, and then during the carbonization and activation process, the carbon dioxide and water generated by the thermal decomposition of hydroxycarbonate were used to have an "in situ gas phase exfoliation". ” action to form micropores and macropore channels; the uniform nano-scale metal oxide particles generated simultaneously after the decomposition of basic carbonate are used as hard templates, and a large number of uniform mesoporous channels are formed after removal by dilute acid etching, thereby A lignin hierarchical porous carbon material with high mesoporosity was obtained. The material has a multi-level pore structure dominated by uniform mesopores and has both macropores and micropores. It can be used as a negative electrode active material for lithium ion batteries, and can simultaneously improve the mass specific capacity, volume specific capacity and rate performance of lithium ion batteries. . |
