摘要
介绍了竹炭的生产工艺、性能及微观结构。竹炭的微观结构非常类似洋葱状富勒烯碳和展开的碳纳米管结构,因而具有许多木炭不具有的特殊功能。由于竹炭具有较大的比表面积,有良好的吸附性能,可用于有害气体的脱除和水体的净化。竹炭的孔隙以大孔为主(200nm),可用作纳米光催化剂或生物膜的载体,制备纳米改性光催化剂杀菌吸附用炭以及可循环使用的生物膜改性竹炭,实现了两种材料两种性能完美的结合,并可解决竹炭吸附饱和的现象。
Production process,properties,and microstructure of bamboo charcoal are briefly introduced.The microstructure of bamboo charcoal is similar to a spreading carbon nanometer tube figure,which endows the charcoal a lot of special functions that wood charcoal has not.Due to bigger specific surface area,bamboo charcoal has good adsorption capacity and can be used to purify air and water.Bamboo charcoal have generally big diameter pores(about 200 nanometer),so it can be used as carrier of nanometer photo catalyst...
