Nanostructured ZnO materials have unique and highly attractive properties and have inspired interest in their research and development. This paper presents a facile method for the preparation of novel ZnO-based nanostructured architectures using a metal organic framework (MOF) as a precursor. In this approach, ZnO nanoparticles and ZnO@C hybrid composites were produced under several heating and atmospheric (air or nitrogen) conditions. The resultant ZnO nanoparticles formed hierarchical aggregates with a three-dimensional cubic morphology, whereas ZnO@C hybrid composites consisted of faceted ZnO crystals embedded within a highly porous carbonaceous species, as determined by several characterization methods. The newly synthesized nanomaterials showed relatively high photocatalytic decomposition activity and significantly enhanced adsorption capacities for organic pollutants.
纳米结构 ZnO 材料具有独特且极具吸引力的性质,激发了人们对其研究和开发的兴趣。本文提出了一种简便的方法,使用金属有机骨架 (MOF) 作为前体制备新型 ZnO 基纳米结构建筑。在这种方法中,在几种加热和大气(空气或氮气)条件下制备了 ZnO 纳米粒子和 ZnO@C 杂化复合材料。通过几种表征方法确定,所得 ZnO 纳米粒子形成了具有三维立方形态的分级聚集体,而 ZnO@C 杂化复合材料则由嵌入在高度多孔碳质物种中的面心立方 ZnO 晶体组成。新合成的纳米材料表现出相对较高的光催化分解活性和显著增强的有机污染物吸附能力。
