摘要

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.
