We report a strategy for the preparation of three dimensional porous carbon materials by activation of different biomass wastes. The three-dimensional porous carbon material has a multi-layer pore structure of large pores, mesopores and small pores. They are arranged in a bridging manner and the multi-layer pore structure can also achieve good conductivity of ions and electrons and large specific surface areas. After 100 cycles, the G-800 sample has a capacity of up to 325 mAh g^-1 at a current density of 0.1 A g^-1. It also exhibits excellent cycle stability. The experimental results show that three-dimensional porous carbon materials prepared by using biomass waste not only solve the problem of disposal of biomass waste, but also obtain methods and ways to produce valuable functional carbon materials on a large scale from waste.

我们报告了通过激活不同的生物质废物来制备三维多孔碳材料的策略。三维多孔碳材料具有大孔，中孔和小孔的多层孔结构。它们以桥接方式排列，并且多层孔结构还可以实现离子和电子的良好导电性以及大的比表面积。100个循环后，将G-800样品的容量的高达325毫安克^-1在0.1 A g的电流密度^-1。它还具有出色的循环稳定性。实验结果表明，利用生物质废物制备三维多孔碳材料不仅解决了生物质废物的处置问题，而且获得了从废物中大规模生产有价值的功能性碳材料的方法和途径。
