摘要: 在对氨基吡啶(p-APD,1.0 mol/L)介质中,140 ℃、12 h条件下采用简单的水热法在锌片上原位合成氧化锌纳米阵列。 用X射线衍射、扫描电子显微镜和高分辨透射电子显微镜(HRTEM)对其晶体结构和形态分别进行了表征和观察,讨论了该氧化锌材料可能的形成机理。 该氧化锌在紫外光照射下对罗丹明B染料具有很强的光催化降解能力。

Abstract: Single crystalline nanoarrays of ZnO were in situ grown on cheap zinc foil at 140 ℃ for 12 h in p-aminopyridine(p-APD, 1.0 mol/L) medium through a simple one-step hydrothermal method. The crystal features and morphology of the products were characterized and observed by X-ray diffraction(XRD), scanning electron microscopy(SEM) and high-resolution transmission electron microscopy(HRTEM), respectively. The possible synthetic mechanism of the ZnO was discussed. The as-prepared ZnO shows a high photocatalytic ability towards the degradation of Rhodamine B under UV irradiation.

Key words: ZnO, nanoarrays, photocatalytic ability
