摘要：采用水热法制备出多层笼状结构的纳米氧化锌。通过XRD、SEM、EDS、TG-DTA等手段对复合前驱体及煅烧产物的结构、组成及形貌进行了表征,并初步探讨了笼状氧化锌的形成机理。结果表明:葡萄糖的引入一方面能够抑制氧化锌晶体的各向异性生长,形成球形的氧化锌产物;另一方面能够作为造孔材料,形成无定形的骨架碳,在后期经过煅烧处理后,便会形成一种多层的笼状结构,同时会在笼壁上形成大量的孔结构。这种具有多孔结构的笼状氧化锌材料有望成为一种高效的光催化剂材料。
Multilayer cage-like zinc oxide nanopowder was prepared by hydrothermal method.Structure,composition,and morphology of the as-synthesized composite precursor and sintering product were characterized by means of XRD,SEM,EDS,and TG-DAT and preliminary discussion was made on the formaiton machenism of cage-like zinc oxide.Results indicated that the introduction of glucose could inhibit the anisotropic growth of zinc oxide crystals and make zinc oxide to form a spherical shape on one hand;being as porecreating material glucose could form amorphous carbon skeleton,and a multilayer cage-like structure will be formed after being calcined on the other hand.This novel porous structural cage-like zinc oxide may have potential application in photocatalyst area.
