摘要
综述了近年来纳米沸石和介孔氧化硅纳米材料的绿色合成方法以及这些材料在环境领域中的应用。重点讨论了这些材料的模板剂循环利用合成法、无模板剂合成法、离子液体合成法、无溶剂合成法以及微波加热合成法等绿色合成技术和方法;同时论述了纳米沸石和介孔氧化硅纳米材料在环境催化以及环境污染物吸附等方面的应用。最后对纳米沸石及介孔氧化硅纳米材料的合成技术新发展和新应用进行了展望。
Nano- zeolites and mesoporous silica nanoparticles are silicate or aluminosilicate nanomaterials with well- defined porous networks,which are widely used in industry applications such as catalysis,separations and gas adsorption.In this review,the recent developments of the greensynthesis of nano- zeolites and mesoporous silica nanomaterials,such as recycling of unused templates,template- free method,synthesis using ionic liquid,solvent-free method and microwave heating method,will be discussed.Environmental applications including environmental catalysis and adsorption of environmental contaminants will also be overviewed.Finally,the new developments of synthesis and the new applications for nano- zeolites and mesoporous silica nanomaterials will be presented.
