摘要
碱土金属硼酸盐由于组成多变、性能优异在众多领域得到广泛应用。近年来,三维组装多级多孔结构纳米碱土金属硼酸盐因其特有结构及优异性能而备受人们关注,但如何实现碱土金属硼酸盐三维多级组装目前还鲜有报道。本文介绍了课题组最近几年利用湿化学法在镁、钙、钡等碱土金属硼酸盐三维组装多级结构,包括MgBO_2(OH)/Mg_2B_2O_5三维多级多孔超结构~~[1]、Ca(BO_2)_2多级多孔微球~~[2]、Ba_2(B_5O_9)Cl·(H_2O)_(0.5)多级微球~~[3]等方面的工作进展,探讨了其可控合成形成机制及在含染料-重金属离子模拟废水处理、基质发光、非均相催化等领域应用前景。
Alkaline metal borates nanostructures have been paid extensive attention in various fields due to their versatile compositions and fantastic properties.And in recent years,three dimensional(3D) nanostructures of alkaline metal borates have attracted much concern owing to the unique structures and novel characteristics.However,it has been rarely reported on the facilely controllable synthesis of the 3D hierarchical porous alkaline metal borates.Herein,some recent advances in our group on the facile synthesis of the 3D porous microspheres of alkaline metal borates were reviewed,including MgBO_2(OH)/Mg_2B_2O_5hierarchical superstructures[1],Ca(BO_2)_2 hierarchical porous microspheres[2]and Ba_2(B_5O_9)Cl·(H_2O)_(0.5)hierarchical microspheres[3],etc.,focusing on the formation mechanism and explorations on the potential applications in dye-/heavy metal ions containing waste water treatment,substrate photoluminescence materials and heterogenous catalysis.
