| 中文摘要: |
| 利用简单的两步合成法制备得到新颖的中孔Ag微米盘(HMDs)/ZnO纳米棒(NRs)异质结,主要包括上晶种和异质外延生长.通过简单的合成参数调控,可以制备不同纳米直径、不同长度、不同形状的ZnO NRs,进而制成不同形貌的Ag/ZnO异质结.结构新颖的Ag/ZnO异质结由一维(1D)半导体和二维(2D)纳米结构元构成,Ag/ZnO异质结具有高比表面积和开放的空间结构,在光电领域具有很重要的应用潜力.在光催化测试中,Ag/ZnO异质结表现出优越的催化活性,主要归因于结构独特的Ag/ZnO异质结的协同效应. |

| Novel heterostructures of Ag holed microdisks(HMDs)/ZnO nanorods(NRs) have been prepared via a two-step aqueous strategy including ZnO seed loading and subsequent heteroepitaxial growth of ZnO NRs on Ag HMDs.By simply adjusting synthetic parameters,ZnO NRs with variable NR diameters,lengths and shapes on Ag HMDs have been realized,which endow Ag/ZnO heterostructures with versatile morphologies.The novel Ag/ZnO heterostructures consisting of integrated 1D semiconductor/2D metal nanostructured blocks with high specific surface area(SSA) and opened spatial architectures may promise important applications related to photoelectric fields.In photocatalytic measurements,the typical Ag/ZnO heterostructure exhibits superior catalytic activity.Synergistic effect of the Ag/ZnO heterostructures contributes to the high catalytic performance. |
