摘要
纳米技术在环境污染治理中具有广泛前景,然而其在应用过程中存在纳米颗粒及活性中心易团聚失活的问题.将纳米粒子的活性中心限制在载体的孔道内,构建出新型纳米限域材料可以有效克服这一缺点.同时,凭借材料的纳米限域效应,一定程度上可影响水的氢键网络结构,并会影响反应中中间活性粒子的演化、传质速率、晶体的生长和成核阶段过程,以及提高局部空间内反应底物的浓度.本文系统梳理了纳米限域材料的制备方法,并对比分析了各种制备方法的优缺点,归纳总结了近年来纳米限域材料在吸附和高级氧化降解污染物中的研究进展,展望了未来纳米限域材料在环境污染物治理领域的研发及应用前景.
Abstract
Nanotechnology holds great promise in environmental pollution control.However,nanoparticles and active centers are prone to agglomerate and deactivate in the process of application.By confining the active center of nanoparticles to the pore of the carrier,a new type of nano-confined material can overcome this shortcoming effectively.Meanwhile,with the nano-confined effect of the material,the hydrogen bond network structure of water can be influenced to some extent,as well as the evolution of intermediate particles in the reaction,mass transfer rates,crystal growth and nucleation stage process.Moreover,the concentration of the reaction substrate in the local space can also be improved by the material.Therefore,this paper systematically reviews the preparation methods of nano-confined materials and compares the advantages and disadvantages of these methods.In addition,the research progress of nano-confined materials in the adsorption and advanced oxidative degradation of pollutants in recent years is concluded.Last but not least,this paper looks into future research and application of nano-confined materials in the field of environmental pollutant treatment.
