本文采用简单的Stober法和有机硅烷定向生长诱导刻蚀法，将水热合成的纳米沸石A包覆在乙基桥连的周期性介孔有机硅（Et-PMO）壳层上，并通过铜离子浸渍法对所得到的蛋黄壳结构的A@Et-PMO纳米复合材料（YS-A@Et-PMO）进行功能化，实现了具有多级孔结构和催化性能的复合材料。对Cu/A和Cu/YS-A@Et-PMO的形貌和金属含量进行了表征。结果表明，Cu/YS-A@Et-PMO复合材料对亚甲基蓝（MB）具有良好的吸附和催化降解性能，对60 mg/L的MB在10 min内的去除率可达95%以上。
In this paper, hydrothermal synthesized nano zeolite A has been encapsulated with ethyl bridged periodic mesoporous organosilica(Et-PMO) shell through a simple modified Stober method and an organosilane-directed growth-induced etching strategy, the obtained yolk-shell structured A@Et-PMO nanocomposite(YS-A@Et-PMO) was further functionalized by the impregnation of copper ions, realizing the composite material with hierarchical porous and catalytic properties. The morphology and metal content of the Cu/A and Cu/YS-A@Et-PMO were fully characterized. As compared to the parent material, the composite Cu/YS-A@Et-PMO has an efficient adsorption and catalytic degradation performance on methylene blue(MB), the removal efficiency reached as high as 95% of 60 mg/L MB within 10 min. These novel structured porous composites may have great potential application for the removal of organic dye including waste effluents.
