摘要
生物质是一种可持续和可再生的生物资源,其具有种类多样、成本低廉和应用广泛等特点。以生物质为基体制备的多孔炭材料可以应用于水处理和电池电极等领域,然而实际应用时存在着缺陷,需要进行改性处理。因此综述了生物质多孔炭改性后特性的变化,并对改性方案进行了总结归纳。从四个方面进行了详细论述,分别是比表面积和孔径的改性、电学性质的改性、官能团的改性和生物活性的改性,这些特性影响着生物质多孔炭的性能和应用效果,分析了这些特性改性方法的优势与不足之处。最后指出了生物质多孔炭改性方法的未来发展方向,以期为生物质多孔炭的改性提供理论支持,为实际应用提供参考依据。
Biomass is a kind of sustainable and renewable biological resources,which has the characteristics of variety,low cost and wide application.The porous carbon materials prepared from biomass can be used in water treatment and battery electrode,but there are some defects in practical application,which need to be modified.Therefore,the change of properties of modified biomass porous carbon was reviewed,and the modification scheme was summarized.The modification of specific surface area and pore size,electrical properties,functional groups and biological activities were discussed in detail,which affected the performance and application effect of biomass porous carbon.The advantages and disadvantages of these modification methods were analyzed.Finally,the future development direction of biomass porous carbon modification methods was pointed out,in order to provide theoretical support for biomass porous carbon modification and provide reference for practical application.
