多孔生物质碳材料的制备及应用研究进展

摘要

Porous biomass carbon is a new functional material derived from saccharides and carbon-rich organic wastes with advantages of large specific area, high porosity, excellent stability and environmental friendliness.One-step carbonization, hydrothermal carbonization and activation method are three common routes to prepare it.In recent years, porous biomass carbon has been utilized in fields of soil improvement, adsorbent and electrode materials, which has attracted great attention of researchers.In this work, carbon sources, synthesis methods as well as applications are introduced.And the research interest of the materials is also discussed.%多孔生物质碳材料是一种由糖类或含碳有机废弃物制备的新型功能材料,具有比表面积大,孔隙率高,性能稳定,绿色环保的优点.其常见的制备工艺有直接碳化法,水热法以及活化法等.近年来,多孔生物质碳材料在土壤改良剂、吸附剂和电极材料等领域的应用受到了研究人员的广泛关注.介绍了多孔生物质碳材料的原料来源、制备工艺和应用情况,并对该材料今后的研究方向提出了建议.
